摘要：

The absorption and luminescence spectra were observed below 77°K by using a high resolution spectrograph. The crystal field spectra show that the structures of some Tm3+ centers are common to both of ZnSe:Tm, Cu and ZnSe:Tm, Li crystals. One of the common centers has a cubic symmetry and the crystal field parameters A40 <r4>=15.1 cm -1 and A60 <r6>=-2.5 cm-1. The Tm3+ ion in this center shows strong emission. Discussions on the model of this center and on the excitation mechanism are given. © 1969, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
