Synthesis, Characterization, and Effect of Increasing Nitrogen Concentration on the Growth of ZnO Nanoparticles

Abstract
Highly crystalline un-doped and doped zinc oxide (ZnO) nanoparticles were synthesized using a coprecipitation method by reaction of zinc acetate with ammonium hydroxide in the presence of urea to obtain N-doped ZnO nanoparticles. X-ray diffraction studies showed the formation of the crystalline phase of Scanning electron microscopy result shows the morphology of the quasispherical particles with the average size of approximately 90nm. UV-visible was carried out to check the luminescent behavior of the synthesized nanoparticles. Fourier transform infrared spectroscopy studies were carried out to take information about different bonds. Our study have showed that with the increase in the concentration of urea not only Nitrogen gets doped into the ZnO nanoparticles but also it acts like a capping agent by decreasing the particle size with increase in concentration.
