Novel Borate-Based UV-Emitting Material: LiSrBO3:Pb2+

Abstract

LiSr_1–xPb_xBO₃ (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.
