Preparation and Luminescence Property Study of Red-Emitting Na_3.6Y_1.8(PO₄)₃:Eu³⁺,Li⁺/K⁺ Phosphors with Excellent Thermal Stability for Light-Conversion Application.

ABSTRACT: A series of red-emitting phosphors, Na_3.6Y_1.8-x(PO₄)₃:xEu³⁺, have been synthesized by a high-temperature solid-phase method. The impact of the partial Li⁺/K⁺ ion substitution on the crystal structure and photoluminescence (PL) performance of Na_3.6Y_1.05(PO₄)₃:0.75Eu³⁺ phosphor have been investigated. Various techniques have been used for characterization of the as-obtained materials. X-ray diffraction (XRD) analysis was utilized to confirm the composites of these samples, and the morphology and element distribution were examined by scanning electron microscope (SEM) and transmission electron microscope (TEM). This study found that the developed Na_3.6
