Comparison of refractive indices of amorphous and crystalline As₂S₃
Method to calculate refractive index and transparency range dispersion of amorphous As₂S₃ is proposed. It is based on effective dielectric permittivity models for porous composite media, comparison of glass and crystal density and use of data on refractive index of the crystal. It is shown that the...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Method to calculate refractive index and transparency range dispersion of amorphous As₂S₃ is proposed. It is based on effective dielectric permittivity models for porous composite media, comparison of glass and crystal density and use of data on refractive index of the crystal. It is shown that the best agreement of calculated and experimental values of refractive index of glass is obtained within the wavelength interval 460 - 670 nm when using Lorenz-Lorentz formula. It is established that As₂S₃ glasses possess pores with filling factor q = 0.057 submerged to isotropic matrix with approximately two times smaller porosity (qm = 0.031). |
