Synthesis and photoluminescence studies of polymer capped SnO2 nanoparticles synthesized by chemical co-precipitation method
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 6
Abstract
In recent years many research works have been focused on the electrical and optical properties of metal oxides. In this present paper SnO2 nanoparticles have been synthesized by chemical co-precipitation method using different capping agents like EDTA (ethylene diamine tetra acetic acid), PVP (polyvinylpyrrolidone), PVA (polyvinyl alcohol) and studied the influence of capping agent on various properties of SnO2 nanoparticles. Structural, surface morphology, chemical analysis and luminescence properties of prepared SnO2 nanoparticles were studied by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) attached with energy dispersive analysis of X-rays (EDAX) and photoluminescence studies (PL). X-ray diffraction study reveals the nano-size particle distribution of the prepared samples with tetragonal rutile structure in the range of 3 to 9 nm. FTIR spectra show the structural confirmation of SnO2 nanoparticles. Various PL signals were observed in the visible region around 375 nm to 600 nm due to oxygen vacancies and interfacial Sn vacancies present in the prepared nanosamples.
