- 論文の詳細を見る
A photo-initiated process via femtosecond pulse induced heterogeneous nucleation in zinc ammine complex (Zn(NH3)42+) based aqueous solution without catalyst and surfactant, followed by thermal treatments for crystal growth into zinc oxide (ZnO) nanorods, was investigated. Hexagonal ZnO nanorods of diameter ≤ 100 nm with smooth planes and length ≤ 1 μm were grown with laser irradiation and successive thermal treatment. The studies show that pH value in the aqueous solutions remarkably effect on morphology of the ZnO nanostructure. Due to the localized high supersaturation of precursor, the hexagonal nucleation was induced by laser irradiation.
