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