Abstract :
The NiO NPs are synthesized by chemical precipitation route at different calcination temperatures 300°C and 400°C. The prepared samples are subjected to powder XRD, SEM, EDS, FTIR and PL analysis. The powder XRD study shows that both NiO NPs have FCC structure. The crystallite size of NiO NPs increases with increase in the calcination temperature. The peaks at 575 cm-1 and 424 cm-1 in FTIR spectra of both the samples are due to the Ni-O stretching vibrations. The SEM analysis reveals that the synthesized NiO NPs are spherical in shape. The average particle size increases with increase in the calcination temperature. The EDS analysis confirms the presence of Ni and O in the synthesized NiO NPs calcinated at 300°C and 400°C. The PL analysis shows that the NiO NPs, calcinated at 300°C and at 400°C, exhibited red emission peaks at 616 nm and 612 nm respectively. The intensity of the emission peaks increase with increasing calcination temperature.
