Investigation of Eu2+ luminescence in barium tetraphosphate Ba3P4O13 polycrystalline ceramics

Abstract
Abstract In this paper, Ba 3 P 4 O 13 :Eu 2+ phosphor was synthesized by a solid-state reaction. The photoluminescence (PL) emission spectrum and luminescence decay kinetics confirm that the doped Eu 2+ ions can occupy two different Ba 2+ sites. The PL excitation spectrum shows a broad band matching well with the emission of near-UV chip. Ba 3 P 4 O 13 :Eu 2+ is a promising phosphor for near-UV chip excited white LEDs. The doped Eu 3+ ions can also be reduced to Eu 2+ ions in air atmosphere at high temperature. Charge compensation mechanism is applied to explain this kind of abnormal reduction.
