Whakaahuatanga Hua
Ko te GOS:Pr/GOS:Tb he rawa uku i tito mai i te gadolinium oxysulfide i whakahohehia e te praseodymium(Pr) te terbium(Tb) hei huānga doping.He pai rawa nga ahuatanga o te scintillation, ka whakamahia nuitia hei rauemi scintillator i roto i nga taputapu atahanga rongoa penei i nga matawai PET.Ko te mahi whakakorikori ko te huri i nga whakaahua kaha-nui, nga matūriki ranei, ki te marama ka kitea.
Ina hikaka ana i te iraruke maiki, ka puta nga ngota gadolinium i roto i te GOS:Pr/GOS:Tb i nga whakaahua, ka kitea e nga kaitirotiro whakaahua.Ma tenei mahi ka taea te atahanga tika me te kite i nga puna radiation.GOS:Pr/GOS: E mohiotia ana a Tb mo to ratou putanga marama teitei, te wa poto o te pirau me te iti o te mura o te rangi, e taea ai te tere me te tika o te kitenga iraruke.He kaha te aukati i nga hihi X me nga hihi gamma, na reira ka tino whai hua ki nga tono whakaahua rongoa.I roto i te katoa, ko te GOS:Pr/GOS:Tb ceramic he rauemi scintillator tino nui kua huri i te waahi o te atahanga rongoa, e arai ana ki te tātaritanga o mua me te rongoa pai ake o nga mate.
