| Summary: | Rutile-phased titanium dioxide nanorods (r-TNRs) and rutile-phased titanium dioxide nanoflowers (r-TNFs) were deposited on fluorine-doped tin oxide coated glass by using one step hydrothermal method at a fixed temperature of 150 °C. The hydrothermal treatment was conducted by varying the reaction time at 2, 3, 4, 5, 6, 7 and 8 h. The effect of reaction time on surface morphology, structure property, crystallite size and Raman spectra was investigated. The nanostructure samples were analysed using X-ray diffractometer, field emission-scanning electron microscope, micro-Raman spectroscopy, and energy-dispersive X-ray spectroscopy. The resulting micro-Raman spectra show abnormal behaviour of Raman intensity. The micro-Raman spectra of the nanostructure samples exhibit insignificant changes and shifting of Raman bands with increasing reaction time. This behaviour can be attributed to the shape and surface morphology distribution of r-TNRs/r-TNFs. © 2016, Springer Science+Business Media New York.
