Chalcogenide glasses systems AS-S, As-Se, As-S-Se and Ge-Se-Te have been prepared and characterised by absorption spectroscopy, scanning electron microscopy and photoluminescence. Photoluminescence spectra have been measured in wide temperature range and the role of multiphonon transitions in mediating the inner 4f-4f electronic transitions was demonstrated. Peculiar Pr related band at 1600 nm has been found in some samples.
