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.
