Structural and Luminescence Behavior of Nanocrystalline Orthophosphate KY(PO): Eu ( = Ca, Sr) Synthesized by Hydrothermal Method.

KY(PO):5% Eu phosphates have been synthesized by a novel hydrothermal method. Spectroscopic, structural, and morphological properties of the obtained samples were investigated by X-ray, TEM, Raman, infrared, absorption, and luminescence studies. The microscopic analysis of the obtained samples showed that the mean diameter of synthesized crystals was about 15 nm.
