Paper Abstract

Transparent conducting coatings have been developed widely as its special optical and electrical properties. It is simple and cheap to deposit the films by dipping coating method from metal hydroxide sol that is formed from inorganic compounds. Two kinds of sol of stannum-doped indium hydroxide and antimony-doped stannic acid are used as starting solution of sol-gel process, and the optical and electrical properties of these films deposited on the alkaline silicate glass by dipping coating method are investigated. Minimum square resistance about 400 (Omega) /(open square) is obtained for stannum-doped indium oxide coatings with transmittance of 75 percent at wavelength of 550 nm. The transmittance of the films in visible spectrum will decrease as the layer thickness increasing. It is observed that surface resistance can decrease rapidly if a barrier layer of silica deposited by dipping from sol-gel process of silicon alkoxide is between the films and the alkaline silicate glass substrate to prevent the alkaline diffusion to the films.
