BaF2 Scintillator, BaF2 crystal, BaF2 scintillation crystal

tlhaloso e khuts'oane:

BaF2 scintillator e na le thepa e ntle ea scintillation le phetisetso ea optical ho feta mefuta e mengata e fapaneng.E nkuoa e le li-scintillator tse lebelo ka ho fetesisa ho fihlela hajoale.Karolo e potlakileng e ka sebelisoa ho lekanya nako ka nepo le ho fumana tharollo ea nako e ntle, e phehelletsoe joalo ka scintillator e tšepisang lipatlisisong tsa pheliso ea positron.E bonts'a boima bo botle ba radiation ho fihlela ho 10⁶rad kapa ho feta.Likristale tsa BaF2 li na le litšobotsi tse ntle tsa scintillation ka lebaka la bokhoni ba tsona ba ho ntša ka nako e le 'ngoe likarolo tsa khanya tse potlakileng le tse liehang, tse nolofalletsang ho lekanya matla ka nako e le 'ngoe ka matla a phahameng le qeto ea nako.Ka hona, BaF2 e na le mefuta e mengata ea litšebeliso mafapheng a fisiks ea matla a phahameng, fisiks ea nyutlelie le meriana ea nyutlelie.

Tlhaloso ea Sehlahisoa

BaF2 e emetse barium fluoride.Ke motsoako o entsoeng ka liathomo tsa barium le fluorine.BaF2 e tiile ka kristale e nang le sebopeho sa cubic 'me e pepesehetse mahlaseli a infrared.Ka lebaka la thepa ea eona e ntle ea phetisetso holim'a mefuta e mengata ea maqhubu, hangata e sebelisoa e le lisebelisoa tsa lilense, lifensetere le li-prism tšimong ea optics.E boetse e sebelisoa ho scintillation detectors, thermoluminescent dosimeters, le lits'ebetso tse ling tse hlokang ho fumanoa ka mahlaseli.BaF2 e na le ntlha e phahameng ea ho qhibiliha 'me ha e qhibilihe metsing, e leng se etsang hore e be lisebelisoa tse molemo mochesong o phahameng le libakeng tse senyang.
