Clustering of rare-earth dopants in GeAs sulfide glasses was studied by fluorescence spectroscopy of Pr-doped glasses and by EPR measurements of Gd-doped samples. The linewidth of the g ~ 2 resonance of Gd 3+ , as well as the relative intensity of emission from the 1 D 2 level of Pr 3+ , was used as a relative measure of rare-earth clustering. Rare earths...
