| He aha ka Europium(III) Oxide i hoʻohana ʻia no? |
Hoʻohana nui ʻia ʻo Europium(III) Oxide (Eu2O3) ma ke ʻano he phosphor ʻulaʻula a polū paha i nā keʻena kīwī a me nā kukui fluorescent, a ma ke ʻano he mea hoʻoikaika no nā phosphor-based yttrium.He mea hana no ka hana aniani fluorescent.Hoʻohana ʻia ka Europium fluorescence i nā phosphors anti-counterfeiting i nā banknotes Euro. He mana nui ka Europium oxide e like me nā mea photoactive no ka degradation photocatalytic o nā mea haumia.
