Study of Concentration Effect on Synthesis ZnO Nanostructures

ZnO nanostructure with hexagonal structures were synthesized using spin coating and hydrothermal methods under variates concentration of seeding and grown solutions. Preferable structure of seeding layer have been choosing according to FESEM result wit0.6 Seeding sol gel concentration. Hexagonal structures of ZnO nanorods have recorded with 0.15g of zinc acetate dehydrate and hexamethylenetetramine. growth solution due to FESEM result. EDS data refer to high purity of synthesis materials which is supported by XRD result. In addition, crystal structure and orientation phase was investigated has agreement with EDS and FESEM results. Optical properties obtained by UV-VIS, to gain 3.72 ev band gap which is close to standard bulk ZnO. Concentration parameter has significant effect on synthesis of ZnO nanostructures
