5g of Ni Nitrate was dissolved in distilled water and stirred for 20 minutes. For 1% Mn doping 0.01213 g of Manganese dioxide (MnO2) was dissolved in distilled water and stirred for 1 hr at 50 o C. The two solutions were mixed and stirred for 2 hrs at 80 o C. 10 ml of NaOH was then added drop by drop for 20 min to cause precipitation. The precipitate was filtered and dried in oven at 100 o C for 6 hrs followed by grinding in Mortar pestle. The characterizations were done using XRD (Proto A-XRD), UV-Vis spectrometer (UV 3600 Plus, Shimadzu, Japan and Photoluminescence spectrometer (Fluromax-4, Horiba Scientific, USA).
