“…As a new optical material, PbWO 4 (PWO) has some specialties, e.g. rather low cost, short radiation length, high irradiative hardness, high density, fast decay time, and chemical stability 1. However, the relative low light yield (LY), which is 30 times lower than that of Bi 4 Ge 3 O 12 , intensively obstructs it for other applications, which require a higher LY.…”
