The impact of the partial Li<sup>+</sup>/K<sup>+</sup> ion substitution on the crystal structure and photoluminescence (PL) performance of Na<sub>3.6</sub>Y<sub>1.05</sub>(PO<sub>4</sub>)<sub>3</sub>:0.75Eu<sup>3+</sup> 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).
