I-substrate ye-BGO
Incazelo
Bi12I-GeO20I-Bismuth germanate crystal iwumsebenzi obalulekile wokwenza ibhendi encane, ukuqina okuphezulu kwesizinda se-SAW/BAW/ idivayisi yesizinda sesikhathi, inkumbulo ebucayi efundwayo bhala i-holographic, amadivaysi ahlobene nesiginali yedijithali nokubambezeleka kokulawula uhlelo.

Incazelo ye-BGO Substrate
I-BGO substrate imele "bismuth germanate" substrate.I-BGO iwumthombo wekristalu ovame ukusetshenziswa njenge-substrate ezinhlelweni ezahlukahlukene zesayensi nezobuchwepheshe.
I-BGO iyimpahla ye-scintillation, okusho ukuthi inamandla okumunca imisebe enamandla amakhulu, njengemisebe ye-gamma, futhi ngaleyo ndlela ikhiphe ama-photon angamandla amancane.Lesi sakhiwo senza i-BGO substrates ilungele ukusetshenziswa kuzitholi zemisebe, i-gamma-ray spectroscopy, namadivayisi ezithombe zezokwelapha.
Ama-substrates e-BGO ngokuvamile amakristalu awodwa akhuliswa kusetshenziswa amasu akhethekile njengendlela ye-Czochralski noma indlela ye-Bridgman-Stockbarger.Lawa makristalu abonisa ukukhanya okuphezulu ekukhanyeni okubonakalayo nokuseduze kwe-infrared, kanye nokuphuma kokukhanya okuhle kakhulu nokulungiswa kwamandla.
Ngenxa yenombolo ye-athomu ephezulu, ama-substrates e-BGO anamandla okumisa aphezulu ngokumelene nemisebe ye-gamma futhi angasetshenziswa ekuvikeleni imisebe nasekutholeni izinhlelo zokusebenza.Zinezinhlobonhlobo zamandla okubona futhi zisebenza kahle kakhulu ekutholeni imisebe ye-gamma enamandla amakhulu.
Ama-substrates e-BGO angasetshenziswa njengenkundla yokukhulisa ezinye izendlalelo zekristalu noma ukufaka amafilimu amancanyana ezinto ezahlukahlukene.Lokhu kuvumela ukuhlanganisa imisebenzi ehlukene nokudala amadivaysi ayinkimbinkimbi kakhulu.
Kafushane, ama-substrates e-BGO ayizinto ezicwebezelayo ezisetshenziswa ezinhlelweni ezihlukahlukene ezihlobene nokutholwa kwe-gamma-ray, i-spectroscopy, izithombe zezokwelapha, nokuvikela imisebe.Anokucaca okuphezulu, ukukhanya okuhle kakhulu, futhi alungele ukuthola imisebe ye-gamma enamandla amakhulu.
