Eu3+扩散钨酸铅晶体(PbWO4)光学性能研究
Study on the Luminescence Properties of Eu3+ Diffused PbWO4 Crystal
摘要
Abstract
The PbWO4 crystal grown by Bridgman method was processed Eu3+ diffusion using ion diffusion method. The influences of Eu3+ diffusion on the luminescence properties of PbWO4 crystal were investigated by the measurements of transmission spectra, luminescence spectra, light yields and luminescence decay time. The results show that the transmittance of Eu3+ diffusion PbWO4 crystal at 350 nm could be significantly improved, the highest luminescence peak at 430 nm is greatly enhanced, the light yield of Eu3+ diffusion PbWO4 with a gate width of 1000 ns can reach 46 pe/MeV, the luminescence decay time is 6. 5 ns.关键词
