Uda, Hashim, Prof. Dr. Jayachandran, M. Md. Eaqub, Ali aismma786@gmail.com Sol–gel combustion Sn-doped indium oxide Structural Electrical Link to publisher's homepage at http://www.journals.elsevier.com Tin-doped indium oxide (ITO) nanoparticles with stable cubic phases were synthesized using a sol–gel combustion method that includes gelation and combustion in organic fuel. The influence of SnO₂ on the phase and morphology of the In₂O₃ nanoparticles were studied by X-ray diffraction, scanning electron microscopy, and high resolution transmission electron microscopy (TEM), along with selected area electron diffraction. ITO nanoparticles with 11–20 nm crystallite size and 69–46 m²⧸g specific surface area were obtained. The lattice constant was nearly 10.12 Å, with orientation along the (222), (400), and (110) planes for all proportions of the doped SnO, indicating a stable cubic phase with high conductivity. The TEM micrograph of the ITO nanoparticles and powder revealed spherical morphology. The microstructure of the cured In₂O₃:Sn with Sn concentrations of 5, 10, 20, and 50 wt% demonstrated that the ITO nanoparticles clustered more densely with the increase in Sn concentration. The gas-sensing ability of the synthesized powders was demonstrated through the sensing of ethanol vapor at 200 °C. 2014-03-14T03:22:03Z 2014-03-14T03:22:03Z 2014-01 Article Ceramics International, vol.40 (1) part B, 2014, pages 1321–1328 0272-8842 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32727 http://www.sciencedirect.com/science/article/pii/S0272884213008067 http://dx.doi.org/10.1016/j.ceramint.2013.07.012 en Elsevier |
