Abstract

New composite materials consisting from arsenic sulphide (As2S3) doped with rare-earth ions (Pr3+) and polyvinyl alcohol (PVA) were prepared and investigated. The optical absorption spectra of thermaly evaporated amorphous thin films of As2S3:Pr3+ correlate with the transmission spectra of bulk glasses. For the samples As2S3:Pr3+/PVA an increasing of transparency in the visible region with respect to pure As2S3 was observed. The investigated new composites are perspective for different photonic devices as we l as for recording media with high resolution..
