Product Description
GOS:Pr/GOS:Tb isimbi yakagadzirwa ne gadolinium oxysulfide inoshandiswa ne praseodymium(Pr) kana terbium(Tb) se doping elements.Iine yakanakisa scintillation zvivakwa, inoshandiswa zvakanyanya se scintillator zvinhu mumidziyo yekufungidzira yekurapa yakadai sePET scanner.Iyo scintillation process inosanganisira kushandura-high-energy photon, kana zvidimbu, kuita chiedza chinooneka.
Kana uchinakidzwa nemwaranzi yechiitiko, maatomu egadolinium muGOS:Pr/GOS:Tb emit photons, anozoonekwa nemafotodetectors.Iyi nzira inobvumira kunyatso kufungidzira uye kuona kwemwaranzi masosi.GOS: Pr/GOS: Tb vanozivikanwa nekubuda kwechiedza chepamusoro, nguva pfupi yekuora uye kuderera kwemashure, zvichigonesa kuona nekukurumidza uye kwakaringana mwaranzi.Iyo ine zvakare yakakwirira yekumisa simba kurwisa X-ray uye gamma rays, zvichiita kuti inyatsoshanda mukurapa imaging application.Pakazere, iyo GOS:Pr/GOS:Tb ceramic chinhu chakakosha chescintillator chakashandura ndima yekufungidzira kwekurapa, zvichitungamira kuongororwa kwekutanga uye kurapwa kwakanyanya kwezvirwere.
