Abstract

We synthesized pure and Pb(2+)ion-doped Li6Gd(BO3)(3)phosphors via the solid-state reaction method at 700(o)C for 5 h in air. The phase analysis of the synthesized materials was determined using DTA/TGA, XRD, and FTIR. The photoluminescence characteristics of pure and Pb2+-doped phosphors were investigated at room temperature using a photoluminescence spectrophotometer. The emission and excitation bands of Pb2+-doped Li6Gd(BO3)(3)were observed at 313 and 242 nm, respectively. The dependence of the PL intensities on the Pb(2+)concentration for the Li6Gd1-xPbx(BO3)(3)(0.005 <= x <= 0.025) phosphors was also studied. The highest emission intensity was obtained from 0.02 mole Pb2+-doped Li6Gd(BO3)(3).
