Product Description
LuAG:Ce (Lutetium Aluminium Garnet-Lu3Al5O12:Ce) cov khoom siv hluav taws xob muaj qhov ntom ntom (6.73g / cm³), muaj Z siab (63) thiab muaj lub sijhawm tawg sai (70ns).Nrog rau qhov nruab nrab siab tshaj emission ntawm 530nm, LuAG: Ce cov zis tau zoo sib xws rau photodiodes avalanche photodiodes APDs thiab silicon photomultipliers (SiPM).Nws yog cov khoom siv hluavtaws crystalline nrog cov qauv cubic uas feem ntau siv los ua cov khoom siv hluav taws xob hauv ntau yam kev siv tshawb fawb, xws li kev kuaj pom thiab kuaj hluav taws xob.Thaum raug ionizing hluav taws xob, LuAG:Ce emits lub teeb, uas tuaj yeem kuaj pom thiab siv los tsim cov duab lossis ntsuas cov qib hluav taws xob.Nws muaj ntau lwm yam zoo heev, xws li siab ceev, loj Zeff thiab zoo txhua yam khoom.LuAG: Ce nyias nyias ua ke nrog FOP thiab CCD tuaj yeem siv tau zoo hauv X-ray microscopy thiab micro-nano CT qhov kev daws teeb meem zoo.Vim nws lub siab kub thiab pob tshab kom muaj zog hluav taws xob, Luac: CE yog muaj txiaj ntsig tshwj xeeb hauv cov ntawv thov thiab rhiab heev, muaj zog ntawm lub cev.Tsis tas li ntawd, LuAG:Ce paub txog nws lub teeb pom kev zoo, lub sijhawm tawg sai, thiab kev daws teeb meem zoo heev, ua rau nws yog qhov kev xaiv nrov rau cov khoom siv hluav taws xob.Tsis tas li ntawd, cov crystals no muaj cov khoom kub zoo.
LuAG: Ce scintillator crystals muaj cov teeb meem hauv qab no uas yuav tsum tau sau tseg.Lawv muaj lub teeb emissions uas yog ib feem zoo yog siab tshaj 500nm, ib cheeb tsam uas photomultipliers tsis tshua rhiab.
Lawv yog cov xov tooj cua intrinsically ua rau nws tsis tsim nyog rau qee daim ntawv thov, thiab raug rau hluav taws xob puas tsuaj, pib nrog koob tshuaj ntawm 1 thiab 10 Grey (10² - 10³ rad).Reversible nrog lub sij hawm los yog annealing.

Cov ntaub ntawv txhawb nqa
1)Kev kuaj mob:Lub thermally stimulated luminescence spectra tau ntsuas nrog Risø TL / OSL-15-B / C spectrometer.Cov qauv tau irradiated nrog β-ray (90Sr raws li hluav taws xob qhov chaw) rau 200 s nrog tus nqi ntawm 0.1 Gy / s.Qhov ntsuas kub yog 5 ° C / s ntawm 30 txog 500 ° C thiab tib lub thickness ntawm cov qauv tau muab tso rau kom ntseeg tau tias cov txiaj ntsig sib piv.
2)Piv txwv:txhua daim duab tuaj yeem hloov kho;xa mus rau TL spectra ntawm keeb kwm yav dhau, thaum cov qauv rhuab ntau dua 400 ° C hauv 700-800 nm tau tshwm sim qauv theem ci (dub-lub cev hluav taws xob);cov ntaub ntawv qub tau ntxiv rau hauv cov khoom siv ntxiv.
