Abstract
In this paper, Ba3P4O13:Eu2+ phosphor was synthesized by a solid-state reaction. The photoluminescence (PL) emission spectrum and luminescence decay kinetics confirm that the doped Eu2+ ions can occupy two different Ba2+ sites. The PL excitation spectrum shows a broad band matching well with the emission of near-UV chip. Ba3P4O13:Eu2+ is a promising phosphor for near-UV chip excited white LEDs. The doped Eu3+ ions can also be reduced to Eu2+ ions in air atmosphere at high temperature. Charge compensation mechanism is applied to explain this kind of abnormal reduction.
