• 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 Tm^<3+> centers are common to both of AnSe:Tm, Cu and ZnSe:Tm, Li crystals. One of the common centers has a cubic symmetry and the crystal field parameters A_4^0<r^4>=15.1 cm^&l;t;-1> and A_6^0<r^6>=-2.5 cm^<1+>. The m^<3+> ion in this center shows strong emission. Discussions on the model of this center and on the excitation mechanism are given.
