Mombamomba ny vokatra
GOS:Pr/GOS:Tb dia akora seramika misy gadolinium oxysulfide ahetsiketsika amin'ny praseodymium(Pr) na terbium(Tb) ho singa doping.Miaraka amin'ny fananana scintillation tena tsara, dia ampiasaina betsaka ho fitaovana scintillator amin'ny fitaovana fitsaboana ara-pitsaboana toy ny scanner PET.Ny fizotry ny scintillation dia ny famadihana ny foton'ny angovo mahery vaika, na ny singa, ho hazavana hita maso.
Rehefa mientanentana amin'ny taratra zava-niseho, ny atôma gadolinium ao amin'ny GOS:Pr/GOS:Tb dia mamoaka fotona, izay hitan'ny photodetectors avy eo.Ity dingana ity dia ahafahan'ny sary mihetsika sy mamantatra ireo loharano taratra.Ny GOS:Pr/GOS:Tb dia fantatra amin'ny famoahana hazavana avo be, ny fotoana simba fohy ary ny fiposahan'ny masoandro, izay ahafahana mamantatra ny taratra haingana sy marina.Izy io koa dia manana hery fijanonana avo amin'ny taratra X sy taratra gamma, ka tena mahomby amin'ny fampiharana sary ara-pitsaboana.Amin'ny ankapobeny, ny seramika GOS: Pr / GOS: Tb dia fitaovana scintillator sarobidy izay nanova ny sehatry ny fitsaboana ara-pitsaboana, nitarika ho amin'ny fitiliana mialoha sy fitsaboana aretina mahomby kokoa.
