| He aha te whakamahinga o te Europium(III) Oxide? |
E whakamahia whānuitia ana te Europium(III) Oxide (Eu2O3) hei phosphor whero, kikorangi rānei i roto i ngā pouaka whakaata me ngā rama fluorescent, hei whakahohe hoki mō ngā phosphor i ahu mai i te yttrium. He kaihoko anō hoki mō te hanga karāhe fluorescent. E whakamahia ana te Europium fluorescence i roto i ngā phosphor anti-rūpahu i roto i ngā moni pepa Euro. He nui te kaha o te Europium oxide hei rauemi photoactive mō te whakahoro i ngā poke rauropi.
