Abstract
SrAl2B2O7:Tb3+ phosphors were fabricated by the sol–gel method. The phosphor showed prominent luminescence in green due to the 5D4–7F5 transition of Tb3+. Structural characterization of the luminescent material was carried out with X-ray powder diffraction (XRD) analysis. Luminescence properties were analyzed by measuring the excitation and photoluminescence spectra. Photoluminescence measurements indicated that the phosphor exhibited bright green emission at about 541 nm under UV excitation. It is shown that the 11% of doping concentration of Tb3+ ions in SrAl2B2O7:Tb3+ phosphors is optimum.
