| Yog Europium (III) oxide siv rau? |
Europium (III) Oxide (EU2O3) tau siv dav los ua cov xim liab lossis cov xim xiav, thiab ua ib qho kev ua kom zoo rau cov phosphor. Nws tseem yog ib tus neeg sawv cev rau kev tsim cov tshuaj fluorescent iav. Europacle fluorescence yog siv nyob rau hauv kev tawm tsam cov ntaub ntawv hauv euro banknotes.europium cov ntaub ntawv rau cov photocataltic accomants.
