Nickel doped zinc oxide nanoparticles produced by hydrothermal decomposition of nickel-doped zinc hydroxide nitrate

Zinc hydroxide nitrate,an anionic exchanger layered material,undoped as well as doped with 2-10% nickel,was synthesized by using a pH-controlled precipitation method.The layered materials were then used to produce the undoped and nickel-doped zinc oxides by hydrothermal-treatment.X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy confirmed the formation of pure phase undoped and nickel-doped layered materials,as well as the products of the hydrothermaltreated materials,nanostructured zinc oxides.Optical studies of the nanostructured zinc oxides showed a decrease in band gap with increasing content of the doping agent,nickel.
