Ingcaciso yeMveliso
I-GOS:Pr/GOS:I-Tb yimathiriyeli ye-ceramic eyenziwe nge-gadolinium oxysulfide evulwe yi-praseodymium(Pr) okanye i-terbium(Tb) njengezinto zedoping.Ngeepropathi ezigqwesileyo ze-scintillation, isetyenziswa ngokubanzi njengezinto ze-scintillator kwizixhobo zokucinga zonyango ezifana ne-PET scanners.Inkqubo yescintillation iquka ukuguqula iiphoton ezinamandla aphezulu, okanye amasuntswana, abe kukukhanya okubonakalayo.
Xa uchulumanciswa yi-radiation radiation, i-gadolinium atoms kwi-GOS:Pr/GOS:Tb emit photons, ezithi ke zichongwe zi-photodetectors.Le nkqubo ivumela umfanekiso ochanekileyo kunye nokufunyanwa kwemithombo yemitha.I-GOS: I-Pr / GOS: I-Tb ziyaziwa ngokuphuma kwazo kokukhanya okuphezulu, ixesha elifutshane lokubola kunye ne-afterglow ephantsi, eyenza ukubonwa kwemitha ngokukhawuleza nangokuchanekileyo.Ikwanawo amandla aphezulu okumisa ngokuchasene ne-X-reyi kunye ne-gamma ray, iyenza isebenze kakhulu kwizicelo zemifanekiso yezonyango.Ngokubanzi, i-GOS:Pr/GOS:Tb i-ceramic sisixhobo esixabisekileyo se-scintillator esithe saguqula icandelo lemifanekiso yonyango, ekhokelela ekuxilongeni kwangaphambili kunye nonyango olusebenzayo lwezifo.
