Rose-like SnO2 Nanostructures Synthesized via Facile Solvothermal Technique and their Optical Properties

Abstract

Rose-like SnO2 nanostructures was successfully synthesized by using ethylenediamine as both an alkali and ligand via solvothermal technique. Quantum size nanocrystalline (2.25nm) was calculated and conformed by XRD and TEM analysis. Rose-like morphology was observed by SEM analysis. The quantum confinement effect was occurred by UV-vis spectroscopy. Room-temperature photoluminescence was carried out and investigated. The growth mechanism of the products is also discussed. The results show that the products have a rose-like SnO2 nanostructure and consist of lot of tiny nanocrystalline, which are good candidates for gas sensor, solar cell and optoelectronic devices.
