Abstract
In essence, this study aims toward understanding the photo-luminescent properties of Dy³⁺ halogenated sulfates, viz., synthesis, characterization, and luminescent behavior of the materials. Dysprosium ions are introduced into the halo-sulfate matrices to investigate their suitability for solid-state lighting applications. The aim of the study is to explain the mechanisms of the photo luminescence of Dy³⁺ and study the influence of the doping concentration on luminescence efficiency and the thermal stability of the emitted light. These will provide a pathway for the further development of advanced luminescent materials with enhanced performance characteristics. This study investigates the luminescent characteristics of rare-earth (RE) doped zinc oxide (ZnO) nanophosphors synthesized via a sol-gel method for potential applications in advanced display and solid-state lighting technologies. ZnO, a wide band gap semiconductor, exhibits tunable optical properties when doped with RE ions, enhancing its photoluminescence (PL) behavior. The incorporation of dopants such as Eu³⁺, Tb³⁺, and Dy³⁺ into the ZnO matrix was explored, with a focus on their impact on structural, morphological, and optical properties. X-ray diffraction (XRD) confirmed the hexagonal wurtzite structure of ZnO with successful incorporation of RE ions. Scanning electron microscopy (SEM) revealed spherical, homogeneously distributed nanoparticles. Photoluminescence analysis indicated strong visible emissions corresponding to the intra-4f transitions of RE ions, superimposed on the ZnO emission band. Enhanced luminescence intensity and spectral tunability were achieved, particularly under UV excitation. These findings demonstrate the potential of RE-doped ZnO nanophosphors in engineering color purity and emission efficiency, making them promising candidates for next-generation display panels and lighting systems. The study underscores the importance of dopant selection and concentration in tailoring nanophosphor performance, contributing valuable insights into the development of high-performance luminescent materials.
