| description | In this paper, a series of structurally modified silicate-substituted apatite co-doped with Sr<sup>2+</sup> and Eu<sup>3+</sup> ions were synthesized by a microwave-assisted hydrothermal method. The concentration of Sr<sup>2+</sup> ions was set at 2 mol% and Eu<sup>3+</sup> ions were established in the range of 0.5–2 mol% in a molar ratio of calcium ion amount. The XRD (X-ray powder diffraction) technique and infrared (FT-IR) spectroscopy were used to characterize the obtained materials. The Kröger–Vink notation was used to explain the possible charge compensation mechanism. Moreover, the study of the spectroscopic properties (emission, emission excitation and emission kinetics) of the obtained materials as a function of optically active ions and annealing temperature was carried out. The luminescence behavior of Eu<sup>3+</sup> ions in the apatite matrix was verified by the Judd–Ofelt (J-O) theory and discussed in detail. The temperature-dependent emission spectra were recorded for the representative materials. Furthermore, the International Commission on Illumination (CIE) chromaticity coordinates and correlated color temperature were determined by the obtained results. |
