Method for improving conductivity and blue light filtering efficiency of transparent conducting oxide (TCO)

A method for improving a conductivity and a blue light filtering efficiency of a transparent conducting oxide (TCO), comprising the following steps:

• placing an indium oxide-based transparent conducting material (TCM) as a sample into a sample chamber of a high-pressure apparatus, and conducting a room-temperature high-pressure treatment, wherein the room-temperature high-pressure treatment refers to compressing the sample to a target pressure of 51 GPa from ambient pressure at room temperature and holding the target pressure for 5 min, and then conducting decompression to the ambient pressure;
• the indium oxide-based TCM is selected from the group consisting of pure indium oxide and indium oxide doped with one of tin, titanium, molybdenum, tungsten, zirconium, and hydrogen;
• and the indium oxide-based TCM has a conductivity of greater than 10 S/m, and an average transmittance of over 75% in visible light at a wavelength of 460 nm to 800 nm.
