摘要：

The excitation spectra of photo- and thermo-luminescence were compared in the VUV-UV spectral region in CaWO4 and PbWO4 scheelite tungstates. Temperature dependences of emission intensities and decay times were measured for PbWO4 in the 80-300 K range and approximated by a simple phenomenological model. The energy level structure of the emission centre excited state and related kinetic processes are discussed for both tungstates.
