| He aha ka mea e hoʻohana ʻia ai ʻo Europium(III) Oxide? |
Hoʻohana nui ʻia ʻo Europium(III) Oxide (Eu2O3) ma ke ʻano he phosphor ʻulaʻula a uliuli paha i nā kīwī a me nā kukui fluorescent, a ma ke ʻano he mea hoʻoulu no nā phosphors i hoʻokumu ʻia i ka yttrium. He mea hana nō hoʻi ia no ka hana ʻana i ke aniani fluorescent. Hoʻohana ʻia ka fluorescence Europium i nā phosphors anti-counterfeiting i nā bila kālā Euro. Loaʻa i ka Europium oxide kahi hiki ke lilo i mea photoactive no ka hoʻohaʻahaʻa photocatalytic o nā mea haumia organik.
