Abstract

The present invention relates to method of raising stability of composite transparent conductive Ag-base film and belongs to the field of film material and film optics. In the sandwiched multilayer TiO2 / Ag / TiO2 film structure, one additional Ti layer of 2-3 nm thickness is coated between the metal Ag layer and the base dielectric TiO2 layer, and the Ti layer is used as the optimizing layer between the metal Ag layer and the base dielectric TiO2 layer and can raise the heat stability of the multilayer film structure while producing few influence on the optoelectronic performance of the multilayer film structure.

Description

technical field [0001] The invention relates to a method for improving the stability of a film, in particular to a method for improving the stability of an Ag-based composite transparent conductive film, and belongs to the field of film materials and film optics. Background technique [0002] Since the Ag film has excellent reflective properties in the visible and infrared ranges, and the resistance of the Ag film is very low, using the principle of induced transmission and matching the reasonable dielectric layer can achieve good anti-reflection and anti-reflection in a certain spectral range. It becomes a transparent conductive film. Due to the excellent conductivity of Ag, this film has great advantages in realizing the ultra-low resistance of transparent conductive films. This composite multilayer film can be used in various fields such as low-emissivity (Low-E) glass windows, solar cell electrodes, transparent electrodes of flat panel displays, and electromagnetic shie...
