| Abstract: | A series of PbWO4(PWO) powders, undoped and doped with Y and or Sb, were prepared in air and studied by cathodoluminescence, photoluminescence excitation and emission spectra, and compared with that of undoped and Sb doped PWO single crystals grown by the Bridgman method. The luminescence of PWO prepared in air at high temperature (900° C) is mainly in a broad green band, and its intensity of emission is stronger than that of doped PWO. However the luminescence of PWO:Sb prepared in an oxygen deficient atmosphere is better than undoped PWO. |
