Ibisobanuro ku bicuruzwa
CaF2: Eu ni kirisiti ya scintillator itanga urumuri iyo ihuye nimirasire yingufu nyinshi.Kirisiti igizwe na calcium fluoride hamwe na cubic kristal yububiko hamwe na ion ya europium yasimbuwe muburyo bwa lattice.Kwiyongera kwa europium bitezimbere ibintu bya kristu ya scintillation, bigatuma ikora neza muguhindura imirasire mumucyo.CaF2: Eu ifite ubucucike bwinshi numubare munini wa atome, ibyo bikaba ibikoresho byiza byo kumenya no gusesengura gamma-ray.Byongeye kandi, ifite imbaraga nziza zo gukemura, bivuze ko ishobora gutandukanya ubwoko butandukanye bwimirasire ukurikije urwego rwingufu zabo.CaF2: Eu ikoreshwa cyane mumashusho yubuvuzi, fiziki ya kirimbuzi nibindi bikorwa bisaba imishwarara yo hejuru.
CaF2.Ifite umurongo utyaye kuri 400nm igice kimwe cyuzuza igice cyohereza imyuka
Kwipimisha Imikorere
[1]Ibyuka bihumanya ikirere:"Emission_at_327nm_excitation_1" bihuye no gupima urumuri rwumucyo wa fluorescence uva muri kristu iyo ushimishijwe numucyo kuri 322 nm (hamwe na 1.0 nm kunyerera kuri monochromator).
Uburebure bwumurongo wikigereranyo ni 0.5 nm (slitwidth ya analyseur).
[2]Ibyishimo:"Ibyishimo_at_424nm_ibisabwa_1_mo1" bihuye no gupima fluorescence yasohotse kumuraba uhamye wa 424 nm (0.5 nm slitwidth kuri analyseur) mugihe wasuzumye uburebure bwumurabyo wumucyo ushimishije (0.5 nm kunyerera kuri monochromator).
Photomultiplier (ibara kumasegonda) yakoraga neza munsi yuzuye kuburyo umunzani uhagaze, nubwo utabishaka, ni umurongo.
Nubwo ibyuka bihumanya ikirere kuri Eu: CaF2 biva mubakora inganda zitandukanye birasa, dusanga uburyo bwo kwishima hagati ya 240 na 440 nm bushobora gutandukana cyane hagati yinganda zitandukanye:
buri ruganda rufite umukono wihariye uranga umukono / "igikumwe".Turakeka ko itandukaniro ryerekana urwego rutandukanye rwumwanda / inenge / okiside (valence)
–Kubera ibihe bitandukanye byo gukura no guhuza Eu: CaF2 kristal.
