    The Cu<inf>0.95</inf>Pt<inf>0.05</inf>Fe<inf>0.97</inf>Sn<inf>0.03</inf>O<inf>2</inf> sample has been synthesized by a solid-state reaction to investigate optical properties of materials of transparent conducting oxide. Crystal structure was characterized by XRD. The Seebeck coefficient and electrical conductivity were measured in the high temperature (300 to 860 K), while the XPS and UV-VIS-NIR spectra were analyzed at room temperature. The XRD peaks confirm the samples forming the delafossite structure phase. The Seebeck coefficient reveals the samples displays the p-type conducting. The XPS spectra show the Sn2+ state stabling in this compound. The optical direct gap is 3.45 eV as a visible-transparent material. These results support that the Cu<inf>0.95</inf>Pt<inf>0.05</inf>Fe<inf>0.97</inf>Sn<inf>0.03</inf>O<inf>2</inf> oxide compounds, of which the Cu<sup>1+</sup> and Fe<sup>3+</sup> sites are substituted by the Pt<sup>1+</sup> and Sn<sup>2+</sup> ions respectively, are p-type transparent conducting oxide materials. © (2013) Trans Tech Publications, Switzerland.
