Abstract

Nano-crystalline particles of zinc oxide having different concentration (0.001, 0.002, 0.003) were effectively synthesized via Co-precipitation technique. Increasing the concentration of Zinc, lattice parameter (a) and (c) of crystal lattice increases according to Vegard's Law. Phase identification of ZnO nanoparticle was analyzed via X-ray diffraction (XRD) and absorbance was measured by ultraviolet visible (UV) spectroscopy. Increment of band gap energy values by increasing concentration of Zinc (Zn2+) ions. An absorbance spectrophotometer was utilized to measure the amount of light passing through differently zinc concentrated solutions. The Absorption peak at 370nm was observed. When concentration increases, peak of absorption displays a progressive red shift. The subsequent redshifts, as stated earlier, are consistent with the observed variance in NP sizes. Fourier transform infrared (FTIR) spectra of zinc nanoparticles were investigated in the spectral region of 4000-500 cm-1 . ZnO samples morphology were also analyzed using scanning electron microscope (SEM). Particles with identical and significant tendency of metallic cluster were observed throughout the samples.
