Abstract. Metal nanocrystals are actual objects for the modern biophysics mainly
because of their usage in sensors based on localized surface plasmon resonance (LSPR)
and as active substrates for surface-enhanced spectroscopies. This work deals with the
experimental and theoretical investigation of optical properties of trigonal and hexagonal
Au nanoprisms deposited on the glass substrates. It was confirmed for the studied
structures that the LSPR spectra depend on the crystals shape and size. Theoretical
modeling the optical properties of plasmon-supporting nanoprisms was performed using
the finite-difference time-domain method. The experimentally obtained and theoretically
modeled LSPR spectral positions were found to be different, which can be attributed to a
high spread of nanoprism shapes and sizes in the same sample and to nanocrystals
aggregation effect confirmed by microscopy data. Additionally, the distributions of the
electric field in the vicinity of nanoprisms under the LSPR conditions were simulated,
and a strong field intensity enhancement at the corners of the prisms was demonstrated,
which implies the promising application of such plasmonic nanostructures for surface-
enhanced spectroscopy.

1. Introduction
Localized surface plasmon resonance (LSPR)
phenomenon plays a significant role in the modern nano-
biophysics, especially, due to its promising applications
in biosensing [1], surface-enhanced infrared absorption
(SEIRA) [2] and surface-enhanced Raman spectroscopy
(SERS) [3, 4]. It is known that the spectral position of
LSPR and accompanying local electric field enhance-
ment strongly depend on the shape and size of the
nanoparticles [5], as well as on the interparticle distance
and the level of ordering in the surface-bound
nanoparticle arrays [6]. Therefore, depending on the
plasmon resonance parameters needed, noble metal
nanostructures of different sizes and morphologies are
used as LSPR-supporting materials. For example,
spherical Au nanoparticles of different sizes has been
exploited for the response enhancement of the surface

plasmon resonance sensing system, and the optimal
nanoparticle diameter of 40 nm was reported to give the
best amplification [7]. Henry et al. [8] investigated Ag
nanocube ensembles in water and individual Ag nano-
cubes on the glass substrate and found striking diffe-
rences in respective LSPR spectra due to an expressed
multimodal LSPR excitation in the latter case. Size- and
shape-dependent LSPR properties of noble metal nano-
disks [9], nanorods [10] and nanopyramids [11] have
been also demonstrated. From the theoretical point of
view, optical properties of the plasmonic nanoparticles
are studied by means of analytical and numerical me-
thods to simulate interaction of electromagnetic waves
with nanoparticles. One of the most common analytical
techniques is Mie scattering approach [12], which is
applicable only for the spherical or ellipsoidal particles,
while for the nonspherical nanostructures numerical
methods are usually preferred. One of them is the finite-
difference time-domain method (FDTD) [13], which
advantages and disadvantages have been reported
earlier [14].
In this work, we experimentally investigate the
LSPR properties of chemically synthesized trigonal and
hexagonal Au nanoprisms deposited on the glass
substrates and theoretically simulate LSPR spectra of
these nanostructures by means of the finite-difference
time-domain method. The analysis of local electric field
distribution near the surface of trigonal and hexagonal
Au nanoprisms with different lateral dimensions is also
presented.
2. Microscopy of trigonal and hexagonal Au
nanoprisms deposited on glass substrates
Fabrication technology of the studied samples was
described in the previous work [15]. Briefly, after
synthesis Au nanocrystals were separated from the
disperse medium by centrifugation (centrifuge OPN-8,
800 min
–1
, 60 min), rinsed with distilled water,
precipitate was resuspended in the distilled water. The
crystals suspension washed from the stabilizer was drop-
casted on the glass substrates and dried at the room
temperature. According to the protocol, plain Au
nanoprisms have the shapes of regular triangle, hexagon
and truncated triangle with the average linear size of
100 nm and height of 60 nm.
The microphotographs of the synthesized Au
nanocrystals (Fig. 1a, b), dark field image of large Au
crystal (Fig. 1c) and electron diffraction pattern of the
latter crystal (Fig. 1d) confirming the nanoprism mono-
crystallinity are presented in Fig. 1. The microphoto-
graphs were obtained using transmission electron micro-
scope JEM 100CX (JEOL, Japan) with the accelerating
voltage of U = 100 kV. Optical microscopy of the
samples was performed using OLYMPUS GX-41 micro-
scope (Мelitek-Ukraine, Ukraine) with the ×100
objective in the light field mode. Optical microscopy
revealed a huge spread of nanoprism sizes and the effect
of nanocrystals aggregation (Fig. 1e, f).

3. LSPR in the trigonal and hexagonal Au
nanoprisms deposited on glass substrates
Light extinction spectra of the samples were measured
using the LSPR spectrometer “Nanoplasmon-003”
(V. Lashkaryov Institute of Semiconductor Physics,
NAS of Ukraine).
Light absorbance measurements have shown the
existence of a broad complex absorption band within the
spectral range 500…1000 nm with a distinct peak in the
visible region at 591 nm (Fig. 2). The appearance of this
absorption band can be attributed to the LSPR excitation
in surface-bound Au nanoparticles, while its complex
form and broadening are possibly observed due to
distribution of shapes and sizes of Au nanoparticles with
several dominating geometrical configurations.
To investigate theoretically the LSPR spectra of
trigonal and hexagonal Au nanoprisms, we modelled
the light extinction cross-section spectra for trigonal
Au nanoprisms with side dimensions of 100 nm
(model 1, Fig. 3a), 25 nm (model 1, Fig. 3b), hexagonal
Au nanoprisms with side dimensions of 33 nm
(model 2, Fig. 3a) and 8 nm (model 2, Fig. 3b), which
were obtained by truncation of trigonal nanoprisms to
get regular hexagonal nanoprism. Additionally,
calculations were performed for the combination of
trigonal Au nanoprism with side dimension of 25 nm
and hexagonal Au nanoprism with side dimension of
8 nm with interparticle distance of 30 nm (model 3,
Fig. 3b), which models the influence of nanoprism
shape distribution on the light extinction spectrum. In
all the considered models, nanoprisms were located on
glass substrates and the height of the nanoprisms was
equal to 60 nm. All calculations were performed using
the commercial FDTD package (Lumerical FDTD
Solutions, trial version, Lumerical Solutions, Inc.,
Canada). The experimental absorbance spectrum and
the theoretical extinction cross-section spectra
corresponding to the abovementioned models are
presented in Fig. 3.
As it can be seen from Fig. 3, simulated and
experimental LSPR spectral positions and shapes are
different. This can be explained by several factors
related to the fact that theoretical spectra correspond to
individual nanoparticles and experimental spectrum
characterizes the whole sample. First, the interaction
between the nanoparticles was not taken into account.
Second, the effect of nanoprisms aggregation was
present in the sample. Third, there were a broad
distribution of nanoparticle sizes and several different
nanoparticle shapes in the same sample. However, it
should be noted that the best agreement with the
experimental spectrum was produced by the model 2
(Fig. 3a). Therefore, we can conclude that the
experimentally observed LSPR response results mainly
from the 100 nm hexagonal Au nanoprisms, but the
contribution of Au nanoprisms with other shapes and
sizes is still significant.

4. Electric field distribution in the vicinity of the Au
nanoprisms on glass substrates
From the practical point of view, it is important to
understand the relation between the geometrical
parameters of plasmonic nanostructures and their
performance as optical amplifiers, e.g., for application
in surface-enhanced spectroscopy. To answer the
question what shape and size of the abovementioned
Au nanoprisms can provide higher signal enhancement,
we calculated the electric field intensity distributions
on the top bases of the investigated Au nanoprisms
under the LSPR conditions using the FDTD method.
Simulation results for the Au nanoprism models
mentioned in Section 3 are presented in Figs 5 and 6.
Calculations were performed for two orthogonal
polarizations of the normally incident linearly-
polarized light with the wavelength corresponding to
the LSPR spectral position of the respective Au
nanoprism model.

Fig. 6. The spatial electric field intensity distribution on the top bases of Au nanoprisms: (a), (b) trigonal nanoprism (model 1 in
Fig. 3a); (c), (d) hexagonal nanoprism (model 2 in Fig. 3a). All nanoprisms are located on the glass substrates and illuminated
with orthogonal polarizations of the normally incident linearly-polarized light.
As it can be seen from the obtained electric field
intensity distributions (Fig. 5), there is a great
enhancement of the electric field at the corners of the
nanoprisms (from tens to thousands times, depending on
the nanoprism shape and light polarization). If we
compare the field enhancements at the corners of the
trigonal and hexagonal nanoprisms, we shall see that it is
about 10 times greater for the trigonal nanoprism than
for the hexagonal one. This implies the opportunity to
exploit the trigonal nanoprisms for surface-enhanced
spectroscopy.
To examine how the size of the nanoparticles
influences the enhancement of the electric field, the
same simulation was performed for trigonal and
hexagonal Au nanoprisms of larger size (model 1 and
model 2 in Fig. 3a) (Fig. 6). From these results it is
evident that while the size of the Au nanoprism increases
from 25 to 100 nm (trigonal) and from 8 to 33 nm
(hexagonal), the maximum field intensity enhancement
increases approximately 10-fold.
In summary, the highest local electric field
enhancement among the considered Au nanoprisms, up
to 18000 times, was exhibited by the trigonal Au
nanoprism with side dimension of 100 nm, when they
are illuminated with light polarized normally to one of
the triangular base sides. To achieve the maximum
performance and reproducibility of such nanostructures
for surface-enhanced spectroscopy and LSPR sensing
applications, they should be prepared as highly ordered
nanoparticle arrays with uniform shape and size.
5. Conclusions
In conclusion, it was confirmed for the studied trigonal
and hexagonal Au nanoprisms deposited on the glass
substrates that the LSPR spectra depend on the
nanocrystals shape and size. Experimentally obtained
and theoretically modelled LSPR positions differ due to
the high spread of the Au nanoprism shapes and sizes
and aggregation of the nanocrystals. Local electric field
intensity modeling under the LSPR conditions have
demonstrated the promising potential of Au nanoprisms
for surface-enhanced spectroscopy, with the highest
enhancement provided by a 100 nm trigonal Au
nanoprism on the glass substrate.
