(Ag3AsS3)0,6(As2S3)0,4 thin films were deposited onto a silica substrate by using rapid thermal evaporation. The surfaces of the films were covered with Ag-rich crystalline micrometer-sized cones. The optical transmission spectra of thin films were studied within the temperature range 77 - 300 K. The absorption spectra in the region of its exponential behaviour were analysed, the dispersion dependences of refractive index as well as the temperature dependences of energy position of absorption edge and Urbach energy were investigated.(Ag3AsS3)0,6(As2S3)0,4 thin films deposited using the thermal evaporation technique onto glass substrates previously covered with layers of gold nanoparticles were studied. Optical transmission spectra of the sandwich structure were studied within the temperature range 77 - 300 K. The absorption spectra in the region of its exponential behaviour were analyzed, the dispersion dependences of refractive index as well as the temperature dependences of the energy pseudogap and Urbach energy were investigated. The disordering processes in the sandwich structure were discussed. The comparative analyses of optical parameters in single (Ag3AsS3)0,6(As2S3)0,4 layer and in the sandwich structure were performed.
