Nanosized Eu-Doped NaYSiO Oxyapatite Phosphor: A Comprehensive Insight into Its Hydrothermal Synthesis and Structural, Morphological, Electronic, and Optical Properties.

Detailed analysis covered the optical and structural properties of Eu-doped NaYSiO oxyapatite phosphors, which were obtained via hydrothermal synthesis. X-ray diffraction patterns of NaYSiO:xEu (x = 0, 1, 5, 7, 10 mol% Eu) samples proved a single-phase hexagonal structure ( (176) space group). Differential thermal analysis showed an exothermic peak at 995 °C attributed to the amorphous to crystalline transformation of NaYSiO.
