Effect of NiO Doping on Structural Properties of ZnO

The functional material was formulated by adding the solutions of AR grade Zinc acetate (Zn (O2CCH3) 2 (H2O) 2) and Nickel chloride (NiCl2) with different molar concentration and heated at 100oC. After heating it for 4h a resin like solid product was formed. The solid product was sintered for 4 h at temperature 1000oC, a light green colour solid product was obtained. Then it was milled for 2 h. The structural properties of the prepared powder materials were studied by X-ray analysis. The observed powder materials show the polycrystalline nature and the crystallite size found to be in the range of 22 to 35 nm. Thermogravimetric (TGA) and differential thermal analyses (DTA) of pure ZnO and NiO- doped ZnO samples were carried out. . The TGA analysis shows that t there is no significant % wt. loss in both samples. Hence the doped sample is observed to be stable. The DTA showed the endothermic nature of reactions for both pure and doped ZnO films.
