Synthesis and characterization of ZnO nanoparticles by novel sol gel technique

Abstract

The developments of nano size metal oxide particles are concerned because of their notable advancements and its idiosyncratic nature. Zinc oxide nanoparticles were synthesized using the novel sol-gel technique. The crystalline structure, surface morphology, functional group of the as- synthesized ZnO nanoparticles were characterized by the X Ray Diffraction (XRD) analysis, Fourier Transform InfraRed (FTIR) analysis respectively. The optical properties of the as-synthesized sample are studied by the Ultraviolet Visible Spectrophotometer (UV-VIS). The XRD results revealed that the prepared sample is highly crystalline having wurtzite crystal structure. FTIR spectra peaks showed the characteristic absorption of the ZnO nanoparticles. UV-VIS spectrum showed a typical absorption peak at 355 nm having a wide band gap of 3.3 eV. ZnO being a promising candidate for superior optoelectrical properties meets the global energy concern.
