Measurements of optical properties have been made on alloyed samples of Se and Ge with In prepared under vacuum by quenching the melt into water. The optical transmission spectra of film Se 90 Ge 10Àx In x (x ¼ 2, 4 and 6) were measured in the wavelength range 400-2000 nm by spectrophotometer. It is

The results are presented of a study of the electrical and optical properties of vacuum evaporated amorphous thin films in the Ge0S0Se system. The effect of Te isoelectronic substitution either completely for S to give Ge 2.5 Te 2.5 Se 95 and Ge 5 Te 5 Se 90 or partially for Se to yield Ge 2.
The optical properties of as-deposited Ge x Se 92Àx In 8 (x ¼ 10, 12.5, 15 and 20 at%) have been studied. Various optical constants have been calculated for the studied compositions. The mechanism of the optical absorption follows the rule of non-direct transition. It was found that, the optical ene
