Abstract

Chalcogenide glasses containing Ag are seen as promising alternative materials for many applications, such as optical elements, memories, bio- and chemical- sensors, solid electrolytes and batteries. Thin films were prepared from bulk sample with composition (GeS2)0,8(Ga2S3)0,2, which was obtained by direct synthesis from pure elements. Two methods were used for thin films preparation – thermal evaporation with two different boxes and pulsed laser deposition (PLD). Thin films were characterized by XRD, EDX, UV/VIS spectroscopy and VASE. Thin films prepared by PLD were suitable thanks to good agreement of composition with bulk sample and good optical homogeneity for photoinduced diffusion and dissolution (OIDD) of silver. After OIDD process the thin films containing Ag were characterized by XRD, EDX, UV/VIS spectroscopy and VASE..
