To study the synthesis mechanism and effect of dopant concentration of Fe ion incorporate in SnO2 nanostructured materials

Abstract

Presently the Nanoscience is the principle topic among the Researcher due to drastic properties and size effective advanced applications of nano scale materials in various field of technology. In present paper nanostructured material of Sn1-xFexO2(where x=0.05, 0.1, 0.15) sample have been prepared successfully by using micro-wave-assisted co-precipitation technique followed by sintering at 6000c for six hours and formation of powder sample in agate motar. The structure and morphology of as-synthesized samples and calcined samples have been examined by diffraction through X-Rays, UV-Vis spectroscopy, FTIR spectra and Scanning of samples by electron microscope techniques respectively. The analysis of X-Ray diffraction snapshots proving that the samples are crystalline in nature and calculated grain size estimated by Debye Scherrer’s formulation is 16.2 nm and analyzed structure is tetragonal rutile structure .The Uv visible absorption spectrograph is used to analyze the optical band gap and shows that the red shifting from 4.1 to 3.64 eV in samples with increment of doping concentration .The FTIR transmission spectra of various samples reveals that the incorporation of Fe ion with various oxidation state by replacing position of Sn ion in SnO2 rutile structure with mainly metal oxide peaks at 562cm-1 for SnO2 and 480 cm-1 for Fe2O3.The SEM images shows that the particles are polycrystalline in nature and truncated in shapes.
