Ce: YAG - Crystal Scintillation dị mkpa

Ce: YAG bụ kristal scintillation dị mkpa nwere arụmọrụ scintillation mara mma. Ọ nwere nnukwu luminous arụmọrụ na obosara ngwa anya usu. Uru kachasị ukwuu bụ na ogologo ogologo ya nke luminescence bụ 550nm, nke enwere ike jikọta ya na ngwa nchọpụta dị ka silicon photodiodes. E jiri ya tụnyere CsI kristal scintillation, Ce: YAG scintillation crystal nwere oge ire ere ngwa ngwa, yana Ce: YAG scintillation crystal enweghị ihe na-adịghị mma, nguzogide okpomọkụ dị elu, yana arụmọrụ thermodynamic kwụsiri ike.
