      abstract = {Ni-doped zinc oxide (ZnO) particles were prepared using the co-precipitation method. We studied the changes in structural and optical properties of ZnO nanoparticles at different doping concentration of Ni. X-ray diffraction (XRD) patterns confirm the wurtzite crystal structure of ZnO and polycrystalline nature. Also, XRD date revealed that with an increase in Ni doping level, there is decrease in lattice parameters. The crystallite size decreases with increase in Ni doping concentration confirmed a successfully incorporation of Ni in the ZnO host matrix. The optical property is investigated by UV-Vis spectroscopy and found that the optical band gap values decreased from 3.39 to 3.26 eV after Ni doping because of p-d exchange interaction.},
