Abstract:Pb2+ doped BaAl2B2O7 materials were prepared by a solution combustion synthesis. The phase of the synthesized materials was determined using the powder X-ray diffraction. The photoluminescent properties of Pb2+ doped BaAl2B2O7 materials were investigated using spectrofluorometer at room temperature. The emission and excitation bands of BaAl2B2O7: Pb2+ were observed at 423 and 266 nm, respectively. The dependence of the emission intensity on the Pb2+ concentration for BaAl2B2O7: Pb2+ was investigated. The Stokes shifts of BaAl2B2O7: Pb2+ was calculated to be 13 953 cm−1.
Keywords:Photoluminescene  XRD
