| Maxaa Europium(III) Oxide loo isticmaalaa? |
Europium(III) Oxide (Eu2O3) waxa si weyn loogu isticmaalaa sidii fosfoor cas ama buluug ah oo ku jira telefishannada iyo laambadaha fluorescent, iyo sidii firfircoone loogu talagalay fosfoorrada yttrium-ku-saleysan.Sidoo kale waa wakiilka soo saarista muraayadda fluorescent.Europium fluorescence waxaa loo isticmaalaa fosfooraska-ka-hortagga been-abuurka ah ee ku jira waraaqaha lacagta Euro.
