Paper Abstract

Pulse laser deposition technique was used to deposite (Ag3AsS3)0.6(As2S3)0.4 thin films upon previously prepared gold nanoparticle layers. The optical transmission spectra of sandwich structure based on Ag3AsS3)0.6(As2S3)0.4 thin film and gold nanoparticles were studied in the temperature range 77-300 K. Temperature behaviour of the Urbach absorption edge as well as the temperature dependences of the energy pseudogap and Urbach energy were investigated. The effect of the order-disorder processes on the optical properties of sandwich structure was discussed. Optical parameters of Ag3AsS3)0.6(As2S3)0.4 thin film and sandwich structure based on (Ag3AsS3)0.6(As2S3)0.4 thin film and gold nanoparticles were compared.
