The effect of annealing temperature on the structural, morphological, optical, magnetic and electrochemical properties of spin coated NiO thin films were studied. The XRD analysis shows that all the annealed NiO thin films are cubic structure with (200) preferred orientation. The XPS spectrum indica...
