I-Erbium oxide, eyaziwa nangokuthii-erbium(III) oxideMF:Er2O3, iyinhlanganisela eye yadonsa ukunaka okusabalele emkhakheni wesayensi yezinto ngenxa yezakhiwo zayo eziyingqayizivele. Esinye sezici ezibalulekile zokufunda noma iyiphi inhlanganisela ukuqonda ukwakheka kwayo kwekristalu, njengoba inikeza ukuqonda ngezakhiwo zayo ezingokomzimba namakhemikhali. Endabeni ye-erbium oxide, ukwakheka kwayo kwekristalu kudlala indima ebalulekile ekunqumeni ukuziphatha kwayo nezindlela ezingase zisetshenziswe.
Isakhiwo sekristalu se-erbium oxide singachazwa njenge-cubic lattice enohlelo lwe-cubic (FCC) olugxile ebusweni. Lokhu kusho ukuthi ama-ion e-erbium (Er3+) ahlelwe ngephethini ye-cubic, ama-ion oksijini (O2-) athatha isikhala phakathi kwawo. Isakhiwo se-FCC saziwa ngezinga eliphezulu le-symmetry kanye nokuhlelwa kokupakisha okuzinzile, okunomthelela ekuzinzeni nasekuqineni kwe-erbium oxide crystal.
Amakristalu e-Erbium oxide nawo anezakhiwo ze-dielectric, okuwenza abe usizo kumishini kagesi. Isakhiwo sekristalu ye-FCC sivumela ukudluliswa okuphumelelayo nokuhlakazeka kokukhanya, okwenza i-erbium oxide ibe into efanelekile yokusetshenziswa okubonakalayo njengama-lasers kanye ne-fiber optics. Iphinde ibe nokusimama okuhle kakhulu kwe-thermal, okuyivumela ukuthi isetshenziswe ezindaweni zokushisa okuphezulu.
Ngaphandle kwesakhiwo sekristalu, ubukhulu kanye ne-morphology yezinhlayiya ze-erbium oxide nazo ziyizici ezibalulekile ezithinta ukusebenza kwazo.Er2O3izimpushana zingahlanganiswa kusetshenziswa izindlela ezahlukene, okuhlanganisa imvula, i-sol-gel, nezindlela ze-hydrothermal. Lezi zinqubo zingalawula usayizi wezinhlayiyana nokuma, okubuye kuthinte indawo engaphezulu, ukusebenza kabusha, kanye nezinye izakhiwo ezibonakalayo zezinhlanganisela. Indlela ethile yokuhlanganisa esetshenziswayo ingenziwa ngendlela oyifisayo ukuze kuzuzwe i-morphology oyifunayo futhi kuthuthukiswe ukusebenza kwe-erbium oxide ezinhlelweni ezithile.
Kafushane, isakhiwo crystal ofi-erbium oxidefuthi ilungiselelo layo le-cubic eligxile ebusweni lithinta kakhulu izakhiwo nokuziphatha kwenhlanganisela. Ukuqonda isakhiwo sekristalu kubalulekile ekusebenziseni izakhiwo zayo eziyingqayizivele ezinhlobonhlobo zezinhlelo zokusebenza. Isakhiwo sekristalu se-erbium oxide siyenza ibe yinto ethembisayo enamandla amakhulu ku-optics, electronics neminye imikhakha. Ucwaningo oluqhubekayo kanye nokuqanjwa okusha kule ndawo ngokungangabazeki kuzoholela ekutholweni okusha nasekusetshenzisweni okungokoqobo esikhathini esizayo.
