Shape and size controlled growth of SnO2 nano-particles by efficient approach

•Two types SnO2 particles was grown by ecofriendly hydrothermal method.•Round nanoparticles and elongated rods was synthesized selectively.•Synthesis parameters was optimized for one step synthesis.•The band gap for nanoparticles are less than for elongated rods shape.

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.
