Abstract
In the obtained Sr 3 (PO 4 ) 2 :Eu 2+/3+ powder, the Eu 3+ and Eu 2+ optically active ions coexist as a result of abnormal reduction of Eu 3+ ions that occurs in the air atmosphere. The powder shows an increasing blue emission and decreasing red emission with an increase of ambient temperature.
