摘要： 采用多种高温固相反应途径合成了纯相Ba3BPO7并研究了Ba3BPO7的水解和热稳定性能.研究表明:Ba3BPO7遇水水解,生成Ba3(PO4)2、Ba5(PO4)3OH和Ba(OH)2;TG-DTA表明它是一致熔化合物,熔点在1353℃左右;同时,初步研究了X射线激发Ba3BPO7:RE(RE=Eu3+、Sm3+)的发光性能,表明基质Ba3BPO7与稀土离子之间存在着能量传递.

Abstract: We explored the synthesis methods of Ba3BPO7 by the high temperature solid reaction method; single phase of Ba3BPO7 was obtained with 3:1
molar ratio of BaCO3 and BPO4, 3:1:1molar ratio of BaCO3, NH4H2PO4 and H3BO3, 2:1:1 molar ratio of BaCO3, BaHPO4 and H3BO3, respectively. The hydrolyzation and thermal
stability properties of Ba3BPO7 were investigated. The results show that Ba3BPO7 can react with water and form the final
products of Ba3(PO4)2, Ba5(PO4)3OH and Ba(OH)2; TG-DTA shows that it melts congruently and its melting point is about
1353℃. The X-ray excited luminescent properties of Ba3BPO7 with rare earth activated were also investigated. The results show that
there is energy transfer between the host and rare earth ions.

Key words: alkaline earth borophosphate, hydrolyzation, X-ray excited luminescent properties
