Abstract Zn 1-x Ni x O (x = 0.0, 0.03, 0.06, 0.09, 0.12, 0.15) nanoparticles were prepared by chemical synthesis route using hydroxyoxalate type precursors and thermal decomposition process. All the samples crystallize in hexagonal wurtzite structure. Nickel doping into the ZnO structure was confirmed by Energy Dispersive X-ray (EDX) spectroscopy, High Resolution Transmission Electron Microscopy (HRTEM) and UV-VIS spectroscopy. The absorption spectra show the increase in band gap with increasing doping parameter. Fluorescence (FL) spectra exhibits the excitonic peak at 354 nm relating to near band edge emission for undoped and nickel doped ZnO nanoparticles. The signature of ferromagnetism of the Zn 0.91 Ni 0.09 O sample has been evidenced by SQUID. Dielectric properties and magnetoelectric (ME) coupling of the samples have also been discussed.
