    I-Ce: I-crystal ye-YAG uhlobo olubalulekile lwamakristalu e-scintillation. Uma kuqhathaniswa namanye ama-scintillator angavamile, i-Ce: I-YAG crystal iphethe ukusebenza okukhanyayo okuphezulu kanye ne-pulse ebanzi yokukhanya. Ikakhulukazi, ukuphakama kwayo okungu-550nm, okuhambisana kahle nokuzwela ukuthola ubude besikhathi sokutholwa kwe-silicon photodiode. Ngakho-ke, ilungele kakhulu ama-scintillators ezinto ezithathe i-photodiode njengamtshina kanye nama-scintillator ukuthola izinhlayiya ezikhokhiswa ukukhanya. Ngalesi sikhathi, ukusebenza kahle kokuhlangana okuphezulu kungatholakala. Ngaphezu kwalokho, i-Ce: YAG nayo ingasetshenziswa ngokujwayelekile njenge-phosphor kuma-cathode ray amashubhu kanye nama-diode amhlophe akhanyisa ukukhanya. 
    Inzuzo ye-Nd YAG Rod:
    Ukusebenza kahle kokuhlangana okuphezulu nokutholwa kwe-silicon photodiode
    Ayikho i-afterglow
    Isikhathi sokubola esifushane
    Impahla esitebeleni yomzimba namakhemikhali
