Abstract |
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 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 decreases from
4.21…4.22 eV down to 4.04…4.05 eV with increasing Тs from 250 °C up to 450 °C. |
