dc.description.abstract1The structural and optical propertie of semiconducting oxide nanomaterials offer several possibilities for applications in photocatalytic activities, solar cells and gas sensing owing to their reduced dimensions and large surface/volume ratios as compared to their bulk counterparts. In this study, undoped and Co doped ZnO nanostructures were prepared by a chemical co-precipitation method. The XRD patterns confirmed that all the samples were crystalline with a wurtzite hexagonal phase without forming any additional phases. A drastic change in the morphology from the transformation of spherically shaped nanoparticles (NP’s) to rod-like shaped NP’s after Co doping was revealed by SEM and TEM micrographs. Raman spectra confirmed the presence of a defect associated peak in Co doped ZnO NP’s. A direct correlation of change in surface morphology after Co doping was observed with PL emission, where near band edge emission in undoped ZnO was transformed into strong blue defect emission.pt_BR
