Abstract

The optical properties of GeSe2 were studied in the range from 400 nm to 600 nm, at the temperatures of 300 K, 77 K and 4.2 K. In the absorption spectra, two different regions were noticed, which correspond to the direct and indirect transition. The stepped dependence of absorption coefficient in the region of the indirect transition indicates absorption, that is emission of phonons in the indirect transition. The parameters, characterizing the direct and indirect transition were determined.
