Yog dab tsiHolmium Oxidesiv rau?
Holmium oxideyog ib qho ntawm cov xim siv rau cubic zirconia thiab iav, ua tus qauv calibration rau optical spectrophotometers, ua ib qho tshwj xeeb catalyst, phosphor thiab ib qho khoom siv laser, muab xim daj lossis liab. Nws yog siv rau hauv kev ua cov tsom iav tshwj xeeb xim. Iav uas muaj holmium oxide thiab holmium oxide cov kev daws teeb meem muaj ntau qhov pom kev pom tseeb hauv qhov pom spectral ntau yam. Raws li feem ntau lwm cov oxides ntawm cov khoom tsis tshua muaj, holmium oxide yog siv ua ib qho tshwj xeeb catalyst, phosphor thiab ib qho khoom siv laser. Holmium laser ua haujlwm ntawm qhov ntev ntawm kwv yees li 2.08 micrometres, txawm tias nyob rau hauv pulsed lossis tas mus li regime. Lub laser no yog qhov muag muaj kev nyab xeeb thiab siv rau hauv tshuaj, lidars, cua ceev ntsuas thiab huab cua saib xyuas. Holmium tuaj yeem nqus fission-bred neutrons, nws kuj tseem siv rau hauv nuclear reactors kom tiv thaiv atomic chain reaction los ntawm kev khiav tawm ntawm kev tswj hwm.
