Popis:	Pure and Pb 2+ doped LiSr 4 (BO 3 ) 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 LiSr 4 (BO 3 ) 3 : Pb 2+ were observed at 284 and 328 nm, respectively. The dependence of the emission intensity on the Pb 2+ concentration for the LiSr 4 (BO 3 ) 3 were studied in detail. It was observed that the concentration quenching of Pb 2+ in LiSr 4 (BO 3 ) 3 is 0.005 mol. The Stokes shifts of LiSr 4 (BO 3 ) 3 : Pb 2+ phosphor was calculated to be 4723 cm –1 .
