摘要：

La-doping significantly improves the radiation hardness of PbWO4 against gamma-ray irradiation. The induced absorption coefficient of La-doped samples is as small as 2 m(-1) at 420 nm even at 10(8) rad (10(6) Gy), The radiation-induced phosphorescence is more than three orders of magnitude less in La-doped PbWO4 crystals than in undoped ones.
