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 ɓarna mai 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 fage. 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 ne mai sauri-lalacewa scintillation abu tare da m m Properties, tare da high haske fitarwa (20000 photons / MeV), azumi luminous lalata (~ 70ns), m thermomechanical Properties, kuma luminous ganiya wavelength (540nm) Yana da kyau matching tare da karɓar m raƙuman ruwa (540nm). pulse yana bambanta gamma haskoki da alpha particles, Ce: YAG ya dace da gano abubuwan alpha, electrons da beta rays, da dai sauransu. Kyakkyawan kayan aikin injiniya na ƙwayoyin da aka caje, musamman Ce: YAG single crystal, yana ba da damar shirya fina-finai na bakin ciki tare da kauri na kasa 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.
