Abstract: In this study the preparation, characterization, and photoluminescence properties of the Eu3+-doped apatite compounds have been presented. The Eu3+ ion doped silicate-substituted apatite, Ca 9.9 Eu 0.1 (PO 4) 2 (SiO 4) 4 (OH) 2−x F x where x = 0; 0.8; 1.2; 2.0, was obtained by a microwave-assisted hydrothermal method. A detailed investigation on the heat-treated samples was done by using X-ray diffraction (XRD), scanning electron microscopy energy-dispersive spectrometry (SEM-EDS), transmission electron microscopy (TEM) and Fourier-transform infrared spectroscopy (FT-IR). The luminescence behavior of Eu3+ ion was explored based on excitation and emission spectra as well as luminescence decay profiles. The emission spectra under excitation to the charge-transfer (CT) transition shows the broad band associated with Eu2+ ion emission. The asymmetry parameter (R parameter) and CIE color coordinates were also discussed. • Eu2+/3+ ion doped silicate-substituted hydroxyapatite was successfully synthesized. • Physicochemical analysis confirmed pure-phase of the obtained material. • Structural and morphological analysis confirmed nanosized of the crystallites. • Spectroscopic properties of doping were investigated in detail.
