摘要：

Luminescence from Pr3+ in monoclinic Gd2O3 is reported. Visible emission lines are observed from both P-3(0) and 1D2 levels. Through selective 4f2 --> 4f5d and 4f2 --> 4f2 excitation, three different luminescence spectra are obtained. They are assumed to correspond to the three different Pr3+ sites in the crystal. For these sites, tentative configuration coordinate models are illustrated.
