Three-dimensional crystalline tin dioxide (SnO2) nanostructures have been synthesized herein using a cost-efficient hydrothermal method. Synthesis parameters have been optimized in order to obtain desired morphologies (spherical nanoparticles (NPs) or elongated prismatic nanorods (NRs)). Materials were characterized by X-ray diffraction, electron microscopy techniques, Raman spectroscopy and thermogravimetric techniques to determine the growing mechanism of the nanoparticles. Prismatic SnO2 nanorods were found to present arrangement of flower-like ensembles. The SnO2 final morphology (NPs or NRs) slightly influences band gap values and photo emission wavelengths.
