The excitation spectra of photo- and thermo-luminescence were compared in the VUV - UV spectral region in
and
scheelite tungstates. Temperature dependences of emission intensities and decay times were measured for
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.
