Defects creation under UV irradiation of PbWO4 crystals.


A systematic study of photothermally stimulated defects creation processes is carried out by the thermally stimulated luminescence (TSL) method for a large number of undoped and doped PbWO4 crystals under irradiation at 80-180 K in the 3.4-4.3 eV energy range. The activation energy Ea for the regular exciton state disintegration is found to be approximately… (More)
