Synthesis, Characterization and Effect of Increasing Nitrogen Concentration on the Growth of ZnO Nanoparticles
Highly crystalline ZnO nanoparticles were synthesized using a co-precipitation 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 crystalline hexagonal nitrogen incorporated ZnO. SEM result shows the morphology of the quasi-spherical particles with the average size of 90 nm. UV-Visible and Photoluminescence were carried out to check the luminescent behavior of the synthesized nanoparticles. FTIR studies were carried out to take information about different bonds. Our study showed that with the increase in the concentration of urea not only the Nitrogen gets doped into the ZnO nanoparticles but also it acts like a capping agent by decreasing the particle size with increase in concentration.
