Abstract
The influence of variations in polyethylene glycol molecular weight on the morphology, spectroscopic and thermal properties of flower-like SnO2 nanorod bundles prepared via solvothermal technique
Author(s): J. Jayashainy and P. SagayarajUniform flower-like SnO2 nanoarchitectures built by numerous one-dimensional nanorod bundles are fabricated through a cost effective solvothermal technique by employing Polyethylene Glycol (PEG) as a structure directing agent. The variations in the molecular weight of PEG are found to influence the size, morphology, growth rate and yield of SnO2 nanorods. The crystal structure, morphology and the elemental composition of the resulting nanorods are characterized by powder X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), High-Resolution Transmission Electron Microscopy (HRTEM) and Energy Dispersive X-ray analysis (EDX). The optical property of the product has been explored by UV-Visible absorption, Fourier Transform Infrared (FT-IR) and FT-Raman spectroscopic techniques. FT-Raman peaks confirm the tetragonal rutile phase of SnO2. Thermogravimetric analysis has been performed to determine the thermal stability of the as-prepared samples.
