摘要

LiSr1–xPbxBO3 (x = 0, 0.0025, and 0.005) materials were synthesized at 750°C for 6 h in air. Powder X-ray diffraction and FTIR were used to determine the phase and bond structure of the synthesized LiSrBO3. Spectrofl uorometry was used to investigate the photoluminescence properties of the prepared phosphors at room temperature. LiSrBO3:Pb2+ was found to have emission and excitation bands at 362 and 275 nm, respectively. Finally, the prepared material LiSrBO3:Pb2+ was found to have a Stokes shift of 8739 cm–1, using the excitation band at 275 nm and the emission band at 362 nm. As a result of this work, a new UVA radiation-emitting substance has been introduced to the literature.
