Abstract

Er-doped glassy As 2S 3 and As 2Se 3 films are prepared by vacuum co-evaporation of chalcogenide glass and Er chalcogenide powder. The films display strong 1.54 μm photoluminescence (PL) and keep the possibility of the photostructural transformations and photoinduced anisotropy. The used method is believed to be applied for preparation of different chalcogenide glassy films doped by various rare-earth elements.
