A novel UV-emitting phosphor: LiSr4(BO3)3: Pb2+
Creators
Description
Pure and Pb2+ doped LiSr4(BO3)3 materials were prepared by a solution combustion synthesis method. The phase analysis of all synthesized materials were determined using the powder XRD. The synthesized materials were investigated using spectrofluorometer at room temperature. The excitation and emission bands of LiSr4(BO3)3: Pb2+ were observed at 284 and 328 nm, respectively. The dependence of the emission intensity on the Pb2+ concentration for the LiSr4(BO3)3 were studied in detail. It was observed that the concentration quenching of Pb2+ in LiSr4(BO3)3 is 0.005 mol. The Stokes shifts of LiSr4(BO3)3: Pb2+ phosphor was calculated to be 4723 cm–1. -- Highlights: • A novel UV-emitting phosphor: LiSr4(BO3)3: Pb2+" synthesized for the first time. • The emission band of LiSr4(BO3)3: Pb2+ was observed at 328 nm upon excitation with 284 nm. • LiSr4(BO3)3: Pb2+ is a good phosphor for broadband UV application
