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 thermally 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 well as for recording media with high resolution |
