A study on SB doping in lead tungstate crystals
نویسندگان
چکیده
In this paper, we present results of a study on Sb doping in lead tungstate crystals. The crystal growth by modified Bridgman method is described. The segregation coefficient of Sb ions in lead tungstate crystals was determined. The scintillation emission and longitudinal transmittance spectra, light output, decay kinetics and radiation damage were measured. It is found that Sb doping alone is not sufficient to produce radiation hard lead tungstate crystals, and postgrowth oxygen compensation is required. r 2002 Elsevier Science B.V. All rights reserved.

متن کاملRadiation-induced color centers in La-doped PbWO 4 crystals
This report presents the result of a study on radiation-induced color center densities in La-doped lead tungstate (PbWO 4 ) crystals. The creation and annihilation constants of radiation-induced color centers were determined by using transmittance data measured for a PbWO 4 sample before and during 60Co c-ray irradiation at a dose rate of 15 rad/h. Following a model of color center kinetics, th...
