Abstract

The aim of this study was to investigate the influence of Ca10-x Eux(PO4)6(OH)2, ( xEu=0; 0.05) before and after immersion in simulated body fluid (SBF) for 72 hours. The samples have been investigated by X-Ray Diffraction, FT-IR Spectroscopy, Raman Spectroscopy and Steady-State Photoluminescence. Moreover, it was studied the antibacterial activity of the powders against Staphylococcus aureus and Escherichia coli bacterial strains. Our studies revealed that after soaking in SBF solution, the average crystallite size of the samples increased. Moreover, it was noticed that the luminescence of the samples is strongly influenced by the immersion in SBF solution..
