Correlation Between Structural and Luminescent Properties of Rare-Earth Doped Phosphors

Abstract

This study investigates the correlation between the structural and luminescent properties of rare-earth doped phosphors. By analyzing a series of phosphor samples doped with various rare-earth ions, we explore how the doping affects the crystalline structure and the resulting photoluminescence. The study employs X-ray diffraction (XRD), photoluminescence (PL) spectra, and electron microscopy techniques to study the structural and optical characteristics. Results indicate that the dopant concentration and crystal symmetry significantly influence the emission efficiency and color tuning of the phosphors, opening new avenues for their applications in solid-state lighting and displays.
