摘要：

The diffuse reflectance and luminescence spectra of Y2O2S:Er3+ and Y2O3:Er3+ are studied under selective and polarized laser excitation. The results indicate that the Er3+ luminescence bands of yttrium oxysulfide in the 1.54-mum region are one order of magnitude stronger and broader than those of yttria. Y2O2S:Er3(+) is shown to contain two types of Er-related emission centers differing in the anion environment of the Er3+ ion.
