Structural, morphological and photoluminescence behaviour of Sr10-xBax(PO4)6(OH)2 hydroxyapatite

Abstract

Abstract This paper reports synthesis of Sr10-x(PO4)6(OH)2 with different concentration of Ba2+ ion by co-precipitation method. To enhance the intensity of photoluminescence properties of strontium hydroxyapatite, barium (Ba2+) 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 (PO4) in the synthesized hydroxyapatite. Photoluminescence spectra shows an intense green light emission at 523 nm under 230 nm UV light irradiation.
