Influence of PbF2 and MoO3 on properties of PbWO4 crystals
2004
Abstract The influence of doping (with F, Gd and Mo ions) and co-doping (with F, Gd or F, Gd, Mo ions) of PbWO 4 crystals was investigated. It is shown that even a small amount of specific impurities (especially F ions) causes an important redistribution of the point defects and changes the physical properties of the crystals. The cell parameters were refined from X-ray powder diffraction data. It was found that the cell parameters of F-doped PbWO 4 samples are larger than those of undoped samples. Photoluminescence and optical transmission spectra of pure and doped PbWO 4 were investigated.
