Ibisobanuro ku bicuruzwa
LuAG: Ce (Lutetium Aluminium Garnet-Lu3Al5O12: Ce) kristu ya scintillator ifite ubunini buke (6.73g / cm³), ifite Z ndende (63) kandi ifite igihe cyangirika vuba (70ns).Hamwe n’imyuka yoherezwa hagati ya 530nm, LuAG: Ce isohoka neza ihuye neza na fotodiode avalanche Photodiode APDs na silicon Photomultipliers (SiPM).Nibikoresho bya sintetike ya kristaline ifite imiterere ya cubic isanzwe ikoreshwa nkibikoresho bya scintillation mugukoresha siyanse zitandukanye, nko gufata amashusho yubuvuzi no kumenya imirasire.Iyo ihuye nimirasire ya ionizing, LuAG: Ce itanga urumuri, rushobora kumenyekana no gukoreshwa mugukora amashusho cyangwa gupima urwego rwimirase.Ifite indi mico myinshi myiza, nkubucucike bwinshi, Zeff nini nubukanishi bwiza.LuAG: Ce ibice bito bifatanije na FOP na CCD birashobora gukoreshwa neza muri microscopi ya X-ray na micro-nano CT aho biteganijwe ko habaho imiterere myiza yumwanya.Bitewe n'ubucucike bwinshi no gukorera mu mucyo ku mirasire y’ingufu nyinshi, LuAG: Ce ni ingirakamaro cyane mu bikorwa bisaba ubushishozi bukomeye kandi bworoshye, nk'ubuvuzi bwa kirimbuzi na fiziki y’ingufu nyinshi.Byongeye kandi, LuAG: Ce izwiho gusohora urumuri rwinshi, igihe cyangirika vuba, hamwe n’ingufu nziza cyane, bigatuma ihitamo gukundwa cyane.Mubyongeyeho, kristu zifite ubushyuhe bwiza.
LuAG: Ce scintillator kristal ifite ibibazo bikurikira bigomba kwitonderwa.Bafite imyuka yoroheje igice cyiza kiri hejuru ya 500nm, akarere aho abafotora batumva neza
Zifite amaradiyo akora kuburyo zitemewe kuri porogaramu zimwe na zimwe, kandi zishobora kwangirika kwimirasire, guhera kuri dosiye iri hagati ya 1 na 10 Icyatsi (10² - 10³ rad).Ihindurwa nigihe cyangwa annealing.

Gushyigikira Amakuru
1)Imiterere yikizamini:Ibikoresho bya luminescence byatewe nubushyuhe byapimwe hamwe na Risø TL / OSL-15-B / C.Ingero zashizwemo β-ray (90Sr nkisoko yimirasire) kuri 200 s hamwe nigipimo cya 0.1 Gy / s.Igipimo cyo gushyushya cyari 5 ° C / s kuva 30 kugeza 500 ° C kandi hashyizweho ubunini bumwe bwintangarugero kugirango ibisubizo bigereranywa.
2)Icyitegererezo:amashusho yose arashobora guhindurwa;reba kuri TL yerekanwe inyuma, mugihe icyitegererezo cyashyutswe hejuru ya 400 ° C muri 700-800 nm cyagaragaye icyitegererezo cyerekana urumuri (imirasire yumukara-umubiri);amakuru yumwimerere yongewemo mubikoresho.
