Executive Summary

The authors report here the realization of Zinc Oxide (ZnO) microsphere through a chemical synthesis route. For structural study and analysis, the fabricated structures were characterized using X-Ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM). Their study of optical properties using photoluminescence reveals a strong violet emission which owes to the recombination of an electron in the zinc interstitial and a hole in the valance band. This structure is a new member in ZnO research and they demonstrate the visible emission properties of their chemically synthesized structures.
