Ukusebenzisa i-Rare Earth oxides ukwenza izingilazi ze-Fluorescent
Izinhlelo zokusebenza ze-Rare Earth Elements Izimboni ezimisiwe, njengama-catalyst, ukwenza ingilazi, izibani, ne-metallurgy, sekunesikhathi eside zisebenzisa izakhi zomhlaba ezingavamile.Izimboni ezinjalo, uma zihlanganisiwe, zibalelwa ku-59% wesamba esisetshenziswa emhlabeni wonke.Manje izindawo ezintsha, ezikhula kakhulu, njengama-alloys amabhethri, izitsha zobumba, nozibuthe baphakade, nazo zisebenzisa izakhi zomhlaba eziyivelakancane, ezihlanganisa ezinye ezingama-41%. Izinto Ezingavamile Zomhlaba Ekukhiqizeni Kwengilazi Emkhakheni wokukhiqizwa kwengilazi, ama-earth oxides angavamile sekuyisikhathi eside acwaningwa.Ngokuqondile, ukuthi izakhiwo zengilazi zingashintsha kanjani ngokungezwa kwalezi zinhlanganisela.Usosayensi waseJalimane ogama lakhe lingu-Drossbach waqala lo msebenzi ngeminyaka yawo-1800s lapho egunyaza ilungelo lobunikazi futhi enza ingxube yama-oxides omhlaba ayivelakancane ukuze ingilazi ikhiphe umbala. Nakuba kusesimweni esingahluziwe namanye ama-oxides asemhlabeni ayivelakancane, lokhu kwaba ukusetshenziswa kokuqala kwe-cerium kwezohwebo.I-Cerium yaboniswa ingcono kakhulu ekumunceni i-ultraviolet ngaphandle kokunikeza umbala ngo-1912 nguCrookes waseNgilandi.Lokhu kwenza kube usizo kakhulu ezingilazini zamehlo ezivikelayo. I-Erbium, i-ytterbium, ne-neodymium ama-REE asetshenziswa kakhulu engilazini.Ukuxhumana okubonakalayo kusebenzisa i-erbium-doped silica fiber kakhulu;ukucutshungulwa kwezinto zobunjiniyela kusebenzisa i-ytterbium-doped silica fiber, namalaser engilazi asetshenziselwa ukuhlanganiswa kokuvalelwa okune-inertial kusebenzisa i-neodymium-doped.Ikhono lokushintsha izakhiwo ze-fluorescent zengilazi kungenye yezinto ezisetshenziswa kakhulu ze-REO engilazini. Izakhiwo ze-Fluorescent ezivela ku-Rare Earth oxides Ihlukile ngendlela engase ibonakale ivamile ngayo ngaphansi kokukhanya okubonakalayo futhi ingakhipha imibala egqamile lapho ijatshuliswa amaza obude obuthile, ingilazi ye-fluorescent inezinhlelo eziningi zokusebenza kusukela ekuthwebuleni izithombe zezokwelapha nocwaningo lwe-biomedical, ukuya ekuhloleni imidiya, ukulandelela kanye noqweqwe lwengilazi yobuciko. I-fluorescence ingaqhubeka isebenzisa ama-REO afakwe ngokuqondile ku-matrix yengilazi ngesikhathi sokuncibilika.Ezinye izinto zengilazi ezine-fluorescent coating kuphela zivame ukwehluleka. Ngesikhathi sokukhiqiza, ukwethulwa kwama-ion asemhlabeni angavamile esakhiweni kubangela i-optical glass fluorescence.Ama-electron e-REE aphakanyiselwa esimweni sokujabula lapho umthombo wamandla ongenayo usetshenziselwa ukujabulisa la ma-ion asebenzayo ngokuqondile.Ukukhishwa okukhanyayo kobude obude begagasi namandla aphansi kubuyisela isimo esijabulile esimweni esiphansi. Ezinqubweni zezimboni, lokhu kuwusizo ikakhulukazi njengoba kuvumela ama-microsphere engilazi ye-inorganic ukuthi afakwe eqoqweni ukuze kukhonjwe umenzi kanye nenombolo yelotho yezinhlobo eziningi zemikhiqizo. Ukuthuthwa komkhiqizo akuthintwa ama-microspheres, kodwa umbala othile wokukhanya ukhiqizwa lapho ukukhanya kwe-ultraviolet kukhanya ku-batch, okuvumela ukutholakala okunembile kwezinto ezibonakalayo.Lokhu kungenzeka ngazo zonke izinhlobo zezinto, okuhlanganisa izimpushana, amapulasitiki, amaphepha, noketshezi. Izinhlobonhlobo ezinkulu zinikezwa kuma-microspheres ngokushintsha inani lamapharamitha, njengesilinganiso esinembile se-REO ehlukahlukene, usayizi wezinhlayiyana, ukusatshalaliswa kosayizi wezinhlayiyana, ukwakheka kwamakhemikhali, izici ze-fluorescent, umbala, izici kazibuthe, kanye ne-radioactivity. Kuyasiza futhi ukukhiqiza ama-microspheres e-fluorescent kusuka engilazini njengoba angakwazi ukufakwa kumazinga ahlukahlukene ngama-REO's, amelana nezinga lokushisa eliphezulu, ukucindezeleka okuphezulu, futhi angasebenzi ngamakhemikhali.Uma kuqhathaniswa nama-polymers, aphakeme kuzo zonke lezi zindawo, ezivumela ukuthi zisetshenziswe ekugxilweni okuphansi kakhulu emikhiqizweni. Ukuncibilika okuphansi kwe-REO engilazini ye-silica kuwumkhawulo owodwa ongaba khona njengoba lokhu kungase kuholele ekwakhekeni kwamaqoqo omhlaba angavamile, ikakhulukazi uma ukugxiliswa kwe-doping kukhulu kunokunyibilika kokulinganisa, futhi kudinga isinyathelo esikhethekile ukucindezela ukwakheka kwamaqoqo.
