摘要

In this report, we have synthesized transition metal-doped Zn1 − xAxO (A = Mn, Fe, Co; x = 0.05) nanoparticles using co-precipitation techniques. The experiment investigates the impact of low levels of transition metal doping on the crystal’s structural, morphological, band gap, and photoluminescence properties. Rietveld analysis of X-ray diffraction data reveals the efficient incorporation of transition metal ions at the Zn site, accompanied by minimal lattice deformation. The crystallite size is determined using Debye-Scherrer and Hall-Williamson formulations while scanning electron microscopy (FESEM) is employed to assess particle morphology and size. UV-visible absorption spectra are utilized for band gap and optical measurements through Tauc’s method. Photoluminescence analysis demonstrates efficient blue luminescence and reduced deep-level defects in the transition metal-doped samples. Additionally, the reported compounds exhibit chromaticity coordinates (CIE) in the blue region.
