Abstract
A novel structure of flower-like hierarchical SnO2 architecture consisted of nanorods array was successfully synthesized by facile one-step hydrothermal route only using sodium stannate tetrahydrate solution of ethanol-water mixed solvent. The morphology and microstructure of the hierarchical SnO2 architecture showed that flower-like hierarchical SnO2 architecture with six similar petals were organized by large scale uniformity and ordered dense nanorods arrays with a diameter of 10-15Â nm and length of about 200Â nm. Infrared absorption spectra (IR), Raman spectra and Ultraviolet-visible (UV-vis) absorption spectra were carried out to investigate the optical properties of the flower-like hierarchical SnO2 nanoarrays. The UV-vis spectrum of as-prepared layered SnO2 nanorod array assemblies showed the band gap blue-shifted compared with the band gap of bulk SnO2. A series of peculiar emission band positions of the room temperature photoluminescence properties of the hierarchical SnO2 nanoarrays were observed.
