## Abstract The influence of Cr^3+^ and F^β^ codoping on the defect structures in PbWO~4~ crystal is investigated by Xβray diffraction and Fourier transform infrared (FTIR) spectroscopy and consequently a doping mechanism is proposed that the Cr^3+^ ions predominantly occupy the W^6+^ sites due to

## Abstract The effects of thermal annealing treatment on the spectroscopic properties of Pr^3+^βdoped PbWO~4~ crystals were discussed in detail. The polarized absorption spectra, polarized fluorescence spectra, and fluorescence decay curves of main emission manifolds of the asβgrown and annealed P
In this paper, the absorption spectrum of PbWO 4 :Cr 3+ crystals is measured at room temperature in the wavelength range from 340 to 520 nm. The d-d transitions of Cr 3+ ions in PbWO 4 crystals with tetragonal symmetry are calculated by the crystal-field theory. The theoretical results are in good a
