Usebenzisa umhlaba ongavamile oxides ukwenza izibuko ze-fluorescent
Izicelo zezinto zomhlaba ezingandile Izimboni ezisunguliwe, ezinjengama-catalysts, ama-glassmaking, ukukhanyisa, kanye ne-metallurgy, bebelokhu besebenzisa izinto zomhlaba ezingandile isikhathi eside. Izimboni ezinjalo, lapho zihlanganisiwe, i-akhawunti ngo-59% yokusetshenziswa okuphelele komhlaba wonke. Manje izindawo ezintsha, ezikhula kakhulu, ezinjenge-alloys yebhethri, ubumba, kanye nama-magnets ahlala njalo, nazo zisebenzisa izinto zomhlaba ezingandile, ezibangela amanye ama-41%. Izinto zomhlaba ezingandile ekukhiqizeni ingilazi Emkhakheni wokukhiqizwa kwengilazi, ama-axides angu-Rare Earth Earth Sekuyisikhathi eside afundwe. Ngokucacile, ukuthi izakhiwo zengilazi zingashintsha kanjani ngokufakwa kwalezi zinhlaka. Usosayensi waseJalimane ogama lakhe linguDrossbach waqala lo msebenzi ngawo-1800s lapho enelungelo lobunikazi futhi ekhiqiza ingxube ye-Rare Earth oxides yokuhlobisa ingilazi. Yize ngesimo esiqhekekile namanye ama-Axide Earth areRRE UCerium wakhonjiswa ukuthi muhle kakhulu ekutholweni kwe-ultraviolet ngaphandle kokunikeza umbala ngo-1912 ngama-crookees eNgilandi. Lokhu kwenza kube wusizo kakhulu kwizibuko zamehlo. I-Erbium, i-yterterbium, ne-neodymium yizisu ezisetshenziswa kakhulu engilazini. Ukuxhumana kwe-Optical Kusebenzisa i-Silica Fiber ye-Erbium-doped silica kakhulu; Ukucutshungulwa Kwezinto Zobunjiniyela kusetshenziswa i-yterterbium-doped silica fiber, kanye nama-lasers engilazi asetshenziselwa ukuvalelwa kokuvalelwa kokuvalelwa kusebenza nge-neodmium-doped. Amandla okushintsha izakhiwo ze-fluorescent yengilazi kungenye yezindlela ezibaluleke kakhulu ze-reo engilazini. Izakhiwo ze-Fluorescent ezivela eMhlabeni ongavamile oxides Ihlukile ngendlela yokuthi ingavela ngokujwayelekile ngaphansi kokukhanya okubonakalayo futhi ingakhipha imibala ekhanyayo lapho i-wavelength ethile, ingilazi eminingi inezicelo eziningi ezivela ekuhlolweni kwezokwelapha kanye nokuhlola imidiya, ukulandelela kanye nezinto zengilazi yengilazi. I-fluorescence ingaqhubeka isebenzisa kabusha kabusha kabusha ifakwe kwi-matrix yengilazi ngesikhathi sokuncibilika. Ezinye izinto zeglasi ezinokuhlanganiswa kwe-fluorescent kuvame ukwehluleka. Ngesikhathi sokukhiqiza, ukwethulwa komhlaba wonke ama-Ions ekwakheni kuphumela ku-Optical Glass Fluorescence. Ama-elektroni we-REE aphakanyisiwe esimweni esijabulisayo lapho kusetshenziswa umthombo wamandla ongenayo ukuze ujabulise ama-ion asebenzayo ngqo. Ukukhishwa okukhanyayo kwe-wavelength ende namandla aphansi kubuyisela isimo esijabulisayo esimweni somhlaba. Ezimweni zezimboni, lokhu kusiza kakhulu njengoba kuvumela ama-microsperes we-Inorganic avumela ukuthi afakwe ku-batch ukukhomba umenzi kanye nenombolo yeningi ngezinhlobo zemikhiqizo eziningi. Ukuthuthwa komkhiqizo akuthinteki ngama-mithosroes, kepha kukhiqizwa umbala othile lapho kukhanya khona lapho kukhanya i-ultraviolet kukhanya ku-batch, okuvumela ukubonezwa okunembile kokuqukethwe okumele kunqunywe. Lokhu kungenzeka ngazo zonke izinhlobo zezinto zokwakha, kufaka phakathi ama-powders, amapulasitiki, amaphepha kanye noketshezi. Kuhlinzekwa izinhlobo ezinkulu ezimazingeni ngokushintsha inani lamapharamitha, njengokulinganisa okuqondile kwe-Reo ehlukahlukene, usayizi wezinhlayiyana, ukwabiwa kosayizi wezinhlayiya, imibala, izakhiwo ze-magnetic, kanye nomsakazo kanye nomsakazo. Kuyinzuzo futhi ukukhiqiza ama-mistrorescent ama-fluorescent kusuka engilazini njengoba kungadonswa amazinga ahlukahlukene ane-reoo's, abekezelela amazinga okushisa aphezulu, izingcindezi eziphakeme. Ngokuqhathanisa nama-polymers, aphakeme kuzo zonke lezi zindawo, ezibavumela ukuthi zisetshenziswe ekugxilweni okuphansi kakhulu emikhiqizweni. I-solubility ephansi ephansi yeReo eSilica Glass ingukulinganiselwa okukodwa njengoba lokhu kungaholela ekwakhekeni kwamaqoqo omhlaba angavamile, ikakhulukazi uma ukugcwaliseka kwe-doping kukhulu kune-solubic.
