Rare-earth elements doped chalcogenide glasses and films, promising materials for optoelectronics, photovoltaics or information technologies, were studied in order to determine their physical and optical properties, especially photoluminescence. In our work we focused on Er and Ho doped chalcogenides of stoichiometry 99,8(Ga5Sb10Ge20S65)0.1Ho0.1Er. We synthetized bulk glass and thin films and characterized it with various methods. In the case of thin films we also studied the effects of preparation condition on their properties.
