Development of Complex ZnO-ITO Particles

We synthesized the complex composed of indium tin oxide (ITO) and zinc oxide (ZnO) particles. The ITO was precipitated on the surface of the ZnO particles formed from the chlorides of In and Sn ion. The complex of ITO and ZnO particles was obtained through the hydrothermal treatment of the precursory, heattreatment in air and reduction in hydrogen gas. The complex was confirmed to have a core-shell structure with the ZnO core coated by ITO layer. The film prepared using the complex showed supherior transpararency at the wave range of visible. The film using the complex of ITO/ZnO of 35/65 wt% showed UV absorption property reducing the UV under 400 nm to the strength lower than 7% maintaining the surface resistivity of about 50 kOmega/ 0 .
