Important Implications of the Electrochemical Reduction of ITO

摘要: Abstract The electrochemical reduction of indium tin oxide (ITO) on glass is systematically studied. It revealed that the light absorbance and electric resistance ITO increases upon reduction. Scanning electron microscopy (SEM) images show integrate films dissolve form particles applying negative potentials. consist metallic In Sn, as characterized by X-ray diffraction (XRD) photoelectron spectroscopy (XPS). strongly depends electrolyte conditions, mainly pH anions. onset potential found to shift increases. NO3− ions are significantly inhibit ITO, shifting ca. 500 mV compared with SO42−, Cl− Br−. can also serve inhibitor adding very low concentration Cl−-dominant electrolyte. Moreover, it electrochemically reduced excellent non-linear optical performance, transmittance tuneable time. This suggests a promising useful application ITO.
