My research work focuses on the synthesis and optical characterization of nanophosphors and functional nanomaterials for advanced photonic applications. I employ wet chemical synthesis techniques to prepare lanthanide-doped nanophosphors, optimizing their structural and luminescent properties through detailed characterization using PXRD, FTIR, UV–Vis, SEM, and TEM. My work also explores defect engineering and irradiation effects using gamma rays, X-rays, and swift heavy ions to study and tailor ionoluminescence, photoluminescence, and thermoluminescence behaviors. These investigations aim to enhance material performance for solid-state lighting, white LEDs, photocatalysis, and anti-counterfeiting applications.
