Abstract
Abstract:This study investigates the impact of nitrogen doping on the structural, optical, and electrical properties of zinc oxide (ZnO) nanoparticles synthesized via a chemical precipitation method. Nitrogen-doped ZnO (N:ZnO) nanoparticles were prepared with varying dopant concentrations (0.5%, 1%, and 5%) and thoroughly characterized using XRD, TEM, UVVis spectroscopy, Raman, FTIR, and photoluminescence techniques. XRD analysis confirmed the retention of the hexagonal wurtzite structure across all samples, with minor lattice distortions and crystallite size increases observed upon nitrogen incorporation, particularly beyond 1% doping. TEM and EDAX analysis verified uniform particle morphology and successful nitrogen integration. UVvisible diffuse reflectance spectroscopy revealed a slight blue shift in the optical band gap, attributed to nitrogen-induced defect states and size-dependent quantum confinement effects. Raman and FTIR spectra showed evidence of structural modifications and nitrogen-related vibrational modes. Electrical measurements indicated doping-dependent variations in resistance and capacitance. Overall, nitrogen doping effectively modulates the nanostructural, optical, and electronic characteristics of ZnO, highlighting its potential in tuning material properties for optoelectronic applications.
