A growing interest in the research of chalcogenide glasses can be currently witnessed, which to a large extent is caused by newly opened fields of applications for these materials. Applications in the field of micro- and opto-electronics, xerography

Photoluminescence (PL) studies were carried out on a-Se and a few $Ge_{20}Se_{80-x}Bi_x$ and $Ge_{20}Se_{70-x}Bi_xTe_{10}$ bulk glassy semiconductors at 4.2 K with $Ar^+$ laser as excitation source. While a-Se and samples with lesser at% of Bi show f

We have studied the kinetics of photoinduced effects in nanolayered $Se/As_2S_3$ film by in situ optical absorption measurements, which reveal that photodarkening in these films is followed by photoinduced diffusion. An increase in disorder during ph

Photoinduced interdiffusion was observed with above band gap light in nanolayered Se/As2S3 films. It is discussed in terms of the optical parameters such as band gap, Urbach edge (E-e) [F. Urbach, Phys. Rev. 92, 1324 (1953)], and B-1/2 (Tauc's parame

Optical parameters of chalcogenide glass multilayers with 12–15 nm modulation lengths prepared by thermal evaporation can be changed by laser irradiation. Photoluminescence sPLd studies were carried out on such nonirradiated and irradiated multilay

In this paper, we report our studies on indium-bismuth mixed doping in the $Ge_{10}Se_{90-x-y}In_xBi_y$ glassy system. Out of the four compositions studied in this glassy system, the contribution to the current for the compositions with x=5 and y=10,
