This paper reports synthesis of Sr 10-x (PO 4 ) 6 (OH) 2 with different concentration of Ba 2+ ion by co-precipitation method. To enhance the intensity of photoluminescence properties of strontium hydroxyapatite, barium (Ba 2+ ) ions are incorporated into hydroxyapatite structure. XRD pattern analysis shows single phase hexagonal structure along with space group P63/m. SEM image depicts the deposition of apatite layer on the surface of agglomerated spheroidal grains. FTIR analysis reveals the presence of functional group (PO 4 ) in the synthesized hydroxyapatite. Photoluminescence spectra shows an intense green light emission at 523 nm under 230 nm UV light irradiation.
