Synthesis, Characterization of Nano Tin Oxide via Co-precipitation Method

Abstract

Pure SnO2 nano powders were synthesized by co-precipitation method. The structure, surface, optical, and functional groups were analyzed by X-ray diffraction, FESEM, UV-Vis spectroscopy, FTIR and fluorescence spectra, respectively. The results were compared with pure tin oxide nanoparticle. X-ray analysis shows that the obtained power has tetragonal rutile structure with average crystallite size of 34 nm. Band gap is observed from UV-Vis spectroscopy. Fluorescence spectrum of pure sample detected a strong emission peaks at 634nm due to surface defect and oxygen vacancies in SnO2 nanoparticles.

Enhancements of Structural and Optical Properties of MgO: SnO2 Nanostructure Films

“…The centrifugal force generated by the spinning causes the solution to spread uniformly across the substrate and evaporate, leaving behind a thin film on the surface [17] . MgO:SnO 2 thin films obtained by spin coating have potential applications in various fields, including optoelectronics [18], and gas sensors [19]. The properties of the thin films, such as their thickness, composition, and morphology, can be tuned by adjusting the concentration and ratio of the precursor materials in the solution and the spin-coating parameters, such as spin speed, spin time, and temperature [20].…”
