TECHNOLOGY FOR ENHANCING PERFORMANCE OF PHOTOCATALYST

摘要

PROBLEM TO BE SOLVED: To provide a method for enhancing optical performance such as optical catalytic performance by improving crystallinity of an inorganic optical functional material such as an inorganic optical catalytic material on a substrate.SOLUTION: A surface modification method of an inorganic optical functional material controls a laser irradiation fluence in a range of 30-100 mJ/cmso that a target material may not fuse in a step for processing a precursor on a substrate by UV ray pulse laser irradiation to obtain the inorganic optical functional material. The precursor of the inorganic optical functional material on a substrate is a thin film formed by applying a solution in which nanoparticles of the target material are dispersed to a surface of the substrate.
