| Abstract: | A series of novel inorganic phosphors KBa1−xPbxBP2O8 and K1+xBa1−2xBixBP2O8 (0.01 ⩽ x ⩽ 0.08) were synthesized by using a solid-state reaction technique at high-temperature and their photoluminescence properties were investigated. The dependence of the emission intensity on the Pb2+ and Bi3+ concentration for the KBa1−xPbxBP2O8 and K1+xBa1−2xBixBP2O8 was studied, in which the optimal concentration as well as the critical transfer distance Rc for Pb2+ and Bi3+ was obtained and determined. The as-prepared phosphors can be effectively excited with ultraviolet (UV), and exhibit UV − blue emission with large Stokes shift. The above work indicates these phosphors could be potential candidates for application in UV lamps industry. |
