Lead Tungstate (PbWO4, abbreviated as PWO) crystal is a new scintillation crystal. PbWO4 substrate has a high density, short radiation length, large irradiation hardness, small attenuation constant, both price and performance are excellent, so it is a highly popular high-energy radiation detection material. 

 

PbWO4 crystal has the characteristics of fast luminescence, high density and high irradiance. PbWO4 single crystal is widely used in high-energy physics detection devices and has broad application prospects in nuclear medicine. Due to its good optical properties and stable physical and chemical properties, PbWO4 substrate is also an excellent photovoltaic crystal material.
