✦ Synopsis
C'halcogenidc glasses of the composition 0.7GazS3.0.27La2S3.0.03Nd2S3 doped by 3 mol c/o of Nd3* were prepmed. T& sbsorption and cmission spectra of these gfasses were compared to those of commercial ED-2 3.1 wt.'+% Nddoped silicate gktss. The absorption intensities of Nd3* in chalcogenïdc glass are higher than in silicate glass due to the increasing covalency of Ir;d'* in these giasses. Because of the low phonon frequency of the chaicogende gJasses non~diative relaxations from the %s,a. *IJ e,i to thc 4F31a are lower thrm in other ouide gtasses and so fluoiescence from this state is obscrued.
