Synthesis and photoluminescence properties of Pb2+ doped SrAl2B2O7

Nanopowders of Pb2+ doped SrAl2B2O7 materials were synthesized by a solution-combustion method using metal nitrates and urea as fuel. The synthesized materials were determined by the powder X-ray diffraction. The microstructure of the synthesized materials was investigated using scanning electron microscopy. The photoluminescent properties of Pb2+ doped SrAl2B2O7 materials were studied using spectrofluorometer at room temperature. The emission and excitation peaks of SrAl2B2O7:Pb2+ were observed at 420 and 277 nm, respectively. The Stokes shifts of SrAl2B2O7:Pb2+ were calculated to be 12,292 cm−1. The dependence of the emission intensity on the Pb2+ concentration for SrAl2B2O7:Pb2+ was investigated.
