Abstract

The decrease of photoluminiscence (PL) intensity under continuous excitation in powdered crystalline GeSe2 was observed at 77 K. The intensity of PL decreased by ∼ 50 % in 2.103s. The characteristics of the PL band for the powdered samples at 77 K are identical with those for crystals, but the temperature dependence of the PL intensity and the peak of the PL spectrum in the temperature range 77-200 K for powdered and bulk crystalline samples are different.
