Ce: YAG - Muhimmiyar Scintillation Crystal

Ce: YAG muhimmin kristal scintillation tare da kyakkyawan aikin scintillation.Yana da babban inganci mai haske da faffadan bugun bugun gani.Babban fa'idar ita ce tsakiyar tsayin hasken sa shine 550nm, wanda za'a iya haɗa shi da kyau tare da kayan ganowa kamar silicon photodiodes.Idan aka kwatanta da kristal scintillation CsI, Ce: YAG scintillation crystal yana da saurin lalacewa lokaci, kuma Ce: YAG scintillation crystal ba shi da ƙoshin ƙarfi, juriya mai zafin jiki, da ingantaccen aikin thermodynamic.Ana amfani da shi musamman wajen gano barbashi haske, gano ƙwayoyin alpha, gano gamma ray da sauran fannoni.Bugu da ƙari, ana iya amfani da shi a cikin gano hoto na lantarki (SEM), babban allo mai kyalli mai kyalli da sauran filayen.Saboda ƙananan rarrabuwa na Ce ions a cikin YAG matrix (kimanin 0.1), yana da wuya a haɗa Ce ions cikin lu'ulu'u na YAG, kuma wahalar haɓakar kristal yana ƙaruwa sosai tare da haɓaka diamita na crystal.
Ce: YAG guda crystal abu ne mai saurin ruɓewa tare da ingantattun kaddarorin, tare da fitowar haske mai girma (20000 photons / MeV), lalatawar haske mai sauri (~ 70ns), kyawawan kaddarorin thermomechanical, da tsayin tsayin tsayin haske (540nm) Yana da kyau Daidaita da karɓar m zango na talakawa photomultiplier tube (PMT) da silicon photodiode (PD), mai kyau haske bugun jini bambanta gamma haskoki da alpha barbashi, Ce: YAG ya dace da gano alpha barbashi, electrons da beta haskoki, da dai sauransu The kyau inji. kaddarorin da aka caje, musamman Ce: YAG crystal single, suna ba da damar shirya fina-finai na bakin ciki tare da kauri na ƙasa da 30um.Ce: YAG scintillation detectors ana amfani da ko'ina a electron microscopy, beta da X-ray kirgawa, electron da X-ray image fuska da sauran filayen.
