Paper Abstract

Results of researches on technology of deposition of thin layers of mixed composition As2(SxSe1-x)3 (0 <x <1), obtained from chemical solutions of separate components As2S3 and As2Se3 are given, and some optical properties (transmittance and recording of holographic information) were studied. The photodarkening of layers and shift of edge of absorption in infra-red (IR) area were found at ultra-violet (UV) and actinic irradiations. The maximum efficiency of holographic writing of diffraction gratings (with Ar laser recording (λ=488 nm)) on thin layers is 2.5 % and after additional processing in the negative etching is 36 %.
