Chemical Synthesis and Optical Properties of ZnO Nanoparticles
We report here a simple wet chemical process to synthesize ZnO nanoparticles. The morphology of the nanoparticles was observed in field emission scanning electron microscope. The nanoparticles have average diameter ~ 100 nm. The optical property of the synthesized ZnO nanoparticles was investigated using UVvisible absorption spectra. The synthesized nanoparticles exhibit strong absorption at ~ ...
متن کاملSynthesis and Optical Properties of ZnO Nanostructures
One-dimensional ZnO nanostructures have great potential applications in the fields of optoelectronic and sensor devices. Therefore, it is really important to realize the controllable growth of one-dimensional ZnO nanostructures and investigate their properties. The main points for this thesis are not only to successfully realize the controllable growth of ZnO nonawires, nanorods and quantum dot...
متن کاملInfluence of Cr dopant on the microstructure and optical properties of ZnO nanorods
One-dimensional (1D) undoped and Cr doped ZnO nanorods with average length of 1 µm and diameter of 80 nm were synthesized using hydrothermal method where a fast growth of ZnO nanorods on the seed layer was observed. Afterwards, the effects of Cr dopant on structural, surface morphology and optical properties of nanorods were studied using X-ray diffraction (XRD), scanning electron microscopy (S...
