Description

technical field [0001] The invention belongs to the field of nano-transparent semiconductor film materials, in particular to a cerium-antimony co-doped tin sol and a preparation method thereof, and a cerium-antimony co-doped tin oxide film and a cerium-antimony co-doped tin oxide film prepared from the sol Tin oxide powder. Background technique [0002] Transparent semiconductor thin films have high visible light transmittance and conductivity, have the characteristics of ultraviolet cutoff, high infrared reflection, strong microwave attenuation, etc., and have been widely used in various optoelectronic devices. Tin oxide (chemical formula: SnO 2 ) is a rutile-type n-type wide bandgap semiconductor with a bandgap of 3.6 eV at room temperature. It is an insulating state at room temperature, has a high resistivity, and its electrical, optical and gas-sensing properties are difficult to meet the requirements of use. In recent decades, people have used doping technology to ob...
