I-Ce: YAG-Ikristale yeScantillation ebalulekileyo

I-Ce: YAG yikristale ebalulekileyo ye-scintillation kunye nokusebenza okugqwesileyo kwe-scintillation. Inokukhanya okuphezulu okuphezulu kunye ne-pulse optical ebanzi. Olona ncedo lukhulu kukuba ubude bayo obusembindini be-luminescence yi-550nm, enokuthi idityaniswe ngempumelelo nezixhobo zokubona ezifana ne-silicon photodiodes. Xa kuthelekiswa ne-CsI scintillation crystal, i-Ce: YAG scintillation crystal inexesha lokubola ngokukhawuleza, kwaye i-Ce: YAG scintillation crystal ayinayo i-deliquescence, ukumelana nobushushu obuphezulu, kunye nokusebenza okuzinzile kwe-thermodynamic. Isetyenziswa kakhulu ekubhaqweni kokukhanya kwamasuntswana, ubhaqo lwamasuntswana e-alpha, ukubhaqwa kwemitha ye-gamma kunye neminye imimandla. Ukongeza, inokuphinda isetyenziswe kumfanekiso wokubona i-electron (SEM), i-high-resolution microscopic imaging fluorescent screen kunye nezinye iinkalo. Ngenxa ye-coefficient encinci yokwahlula kwe-Ce ion kwi-matrix ye-YAG (malunga ne-0.1), kunzima ukubandakanya i-Ce ions kwiikristale ze-YAG, kwaye ubunzima bokukhula kwekristale bukhula ngokukhawuleza ngokunyuka kwe-crystal diameter.
I-Ce: YAG ikristale enye yinto ekhawulezayo yokubola ye-scintillation enezinto ezigqwesileyo ezibanzi, kunye nokukhanya okuphezulu (20000 photons / MeV), ukubola okukhanyayo okukhawulezayo (~ 70ns), iipropathi ezigqwesileyo ze-thermomechanical, kunye nobude obukhanyayo obuphezulu (540nm) Ilungile. ehambelana ne-wavelength efumana uvakalelo lwetyhubhu ye-photomultiplier yesiqhelo (PMT) kunye nesilicon photodiode (PD), i-pulse yokukhanya elungileyo yahlula imitha ye-gamma kunye namasuntswana e-alpha, i-Ce: YAG ilungele ukufumanisa amasuntswana e-alpha, ii-electron kunye nemitha ye-beta, njl. njl. iipropati zamasuntswana ahlawuliweyo, ngakumbi i-Ce: YAG ikristale enye, yenza kube lula ukulungiselela iifilimu ezincinci ezinobunzima obungaphantsi kwe-30um. I-Ce: YAG scintillation detectors zisetyenziswa kakhulu kwi-electron microscopy, i-beta kunye ne-X-reyi yokubala, i-electron kunye ne-X-ray imaging screens kunye nezinye iindawo.
