Abstract

Indium tin oxide (ITO) nanoparticle was synthesized by newly developed low temperature synthetic method. The new method is to synthesize the ITO nanoparticle at low temperature of 300°C instead of conventional synthetic temperature of 700°C. The lowering of the temperature was realized by excluding CI and NO3 that are included in the conventional method. Mean size of ITO nanoparticle is 5 nm and uniformly dispersed. Surface area exceeds 100 m2/g. The crystal structure is cubic with orientation of (222), (400), (440). The concentration ratio of indium and tin is 91 at% and 9 at% in the lattice of the ITO nanoparticle. Also, ITO thin film by Ink jet printing was successfully made using the ultrafine ITO nanoparticle. ITO thin film was uniformly printed with ultrafine nanoparticle. Such a well coated thin film reflected the good optical properties. That is, the optical transmittance exceeds 90%. So, ITO nanoparticle for ink jet printing was successfully developed using newly developed low temperature synthetic method.
