A new long-lasting phosphor Ba3P4O13: Eu2+ has been synthesized through the high temperature solid-state method. The excitation spectrum of Ba2.99P4O13: 0.01Eu(2+) is a broadband from 200 to 450 nm attributed to the 4f(7)-> 4f(6)5d(1) transition of Eu2+ ions. The emission spectrum of Ba2.99P4O13: 0.01Eu(2+) exhibits an asymmetric emission band ascribed to the 4f(7)-> 4f(6)5d(1) transition of Eu2+ ions in two different sites. Under the optimum doping concentration, the long-lasting phosphorescence (LLP) can persist for nearly 85 min at recognizable intensity level (>= 0.32 mcd/m(2)). The mechanism of afterglow is discussed briefly. (C) 2014 The Electrochemical Society. All rights reserved.
