Studies of Luminescence Properties of Eu3+ Ions Doped the Silicate-Substituted Apatite and Co-doped with Strontium Ions

Nanosized silicate-substituted hydroxyapatites doped with Eu3+ ions were synthesized using a microwave assisted hydrothermal method and heat-treated at the temperature of 400 °C. The concentration of optically active Eu3+ ions was established in the range of 0.5–2.0 mol% and the concentration of strontium ions was set to be at 2 mol% in proportion to the overall molar content of calcium ions.. The structure and morphology properties were carried out by X-ray powder diffraction technique and SEM, respectively. The emission, excitation spectra and emission kinetics were measured and analyzed as a function of the concentration.
