Cerium doped Yttrium Aluminium Garnet(Ce:YAG) crystal has high luminous efficiency and wide light pulse, and its luminescence peak (550nm) can well match the sensitive wavelength of the photodiode. It is suitable for the application when using photodiodes as photodetectors and detecting lightly charged particles. Also, it is not deliquescent, high temperature resistant, and stable in thermodynamic properties, and can be used in extreme detection environments.
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.
