Tuairisgeul toraidh
GOS: Pr / GOS: Is e stuth ceirmeag a th’ ann an Tb air a dhèanamh suas de gadolinium oxysulfide air a ghnìomhachadh le praseodymium (Pr) no terbium (Tb) mar eileamaidean dopaidh.Le feartan scintillation sàr-mhath, tha e air a chleachdadh gu farsaing mar stuth scintillator ann an uidheamachd ìomhaighean meidigeach leithid sganaran PET.Tha am pròiseas scintillation a’ toirt a-steach a bhith ag atharrachadh photons àrd-lùth, no mìrean, gu solas faicsinneach.
Nuair a bhios e air bhioran le rèididheachd tachartas, bidh dadolinium atoms ann an GOS:Pr/GOS:Tb a’ leigeil a-mach photons, a bhios an uairsin gan lorg le photodetectors.Tha am pròiseas seo a’ ceadachadh ìomhaighean mionaideach agus lorg stòran rèididheachd.Tha GOS: Pr / GOS: Tb ainmeil airson an toradh solais àrd, ùine lobhadh goirid agus afterglow ìosal, a’ comasachadh lorg rèididheachd luath agus ceart.Tha cumhachd stad àrd aige cuideachd an aghaidh ghathan-X agus ghathan gamma, ga dhèanamh gu math èifeachdach ann an tagraidhean ìomhaighean meidigeach.Gu h-iomlan, tha an ceirmeag GOS: Pr/GOS:Tb na stuth luachmhor scintillator a tha air raon ìomhaighean meidigeach ath-nuadhachadh, a’ leantainn gu breithneachadh nas tràithe agus làimhseachadh ghalaran nas èifeachdaiche.
