| Europium (III) Oxide siv rau dab tsi? |
Europium (III) Oxide (Eu2O3) yog dav siv los ua liab lossis xiav phosphor hauv TV teeb thiab fluorescent teeb, thiab ua tus activator rau yttrium-based phosphors. Nws tseem yog tus neeg sawv cev rau kev tsim cov iav fluorescent. Europium fluorescence yog siv los tiv thaiv phosphors hauv cov ntawv pov thawj Euro.Europium oxide muaj peev xwm ua tau zoo li cov ntaub ntawv siv rau photocatalytic degradation ntawm cov organic pollutants.
