Abstract: Pb2+ doped SrAl2B2O7 was prepared by solution combustion synthesis. The synthesized material was determined by powder XRD. The photoluminescence properties of the synthesized phosphor were investigated at room temperature using a spectrofluorometer. The emission peak of Pb2+ doped SrAl2B2O7 was observed at 420 nm upon excitation at 277 nm. The Stokes shift of SrAl2B2O7:Pb2+ was calculated to be 12 292 cm−1. The luminescence behavior of Pb2+ in both SrAl2B2O7 and CaAl2B2O7 was discussed. [ABSTRACT FROM AUTHOR]
