Title: Ba{sub 3}BP{sub 3}O{sub 12}:Eu{sup 2+}--A potential scintillation material

Abstract

The sample of Eu{sup 2+}-doped Ba{sub 3}BP{sub 3}O{sub 12} was prepared by a solid-state reaction at high temperature and was showed to be an excellent scintillator when excited with hard x ray s. The phosphor showed a broad emission band in the wavelength range of 400-650 nm and a comparable light yield with that of Bi{sub 4}Ge{sub 3}O{sub 12} powders. Its room temperature fluorescence decay curve exhibited a two-exponent shape with decay time of 20.0{+-}1.4 ns (98.97%) and 522{+-}9 ns (1.03%), respectively. Considering the suitable emission wavelength range, large light yield, short decay time, moderate density, moderately low melting point, and nonhygroscopic property of Ba{sub 3}BP{sub 3}O{sub 12}:Eu{sup 2+}, one has reason to assume that this compound might find an application as a new scintillation material.
