Af. Maged et al., OPTICAL-ABSORPTION OF AMORPHOUS-SEMICONDUCTORS GE20AS30SE50-XTEX AND THE EFFECT OF GAMMA-IRRADIATION, Materials chemistry and physics, 56(2), 1998, pp. 184-188
The Ge-As-Se system has been selected as the basic glass system for st
udying the effects of addition of tellurium on transition temperature,
density, molar volume and optical properties. The effect of gamma-irr
adiation on IR transmission for the systems x = 0 and x = 40 has been
studied. Oxygen impurities, which are increased after gamma-irradiatio
n, produce an absorption between 12 and 16 mu m due to Ge-O, AsO and S
e-O. (C) 1998 Elsevier Science S.A. All rights reserved.
