Determination of fundamental optical constants of Zn₂SnO₄ films
Examined in this paper have been optical properties of polycrystalline films Zn₂SnO₄ deposited using the spray pyrolysis method within the range of substrate temperatures 250 °C to 450 °C in increments of 50 °C. The spectral dependences have been found for the following physical quantities: k(λ), n(...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Examined in this paper have been optical properties of polycrystalline films Zn₂SnO₄ deposited using the spray pyrolysis method within the range of substrate temperatures 250 °C to 450 °C in increments of 50 °C. The spectral dependences have been found for the following physical quantities: k(λ), n(λ), ε1(λ), ε2(λ), and are defined as they change under the influence of substrate temperature Тs. Moreover, using the model by Wemple–DiDomenico, it was calculated the dispersion energy Ео and Ed for this oxide. Two independent methods defined band gaps Zn₂SnO₄, which decrease from 4.21…4.22 eV down to 4.04…4.05 eV with increasing Тs from 250 °C up to 450 °C.
