Abstract

The invention discloses a preparation method of a thorn-ball photochromic MoO3 thin film. The preparation method comprises the following steps: (1) preparing a 0.05-3mol / L molybdate liquor; (2) adding a formaldehyde liquor to the molybdate liquor, adjusting the pH of the liquor by a pH adjustor to 0.8-1.5, and stirring and homogenizing in dark light; (3) transferring the homogenized reaction liquor to a reaction container, and placing a clean transparent conductive oxide crystal substrate for hydrothermal reaction; (4) after hydrothermal reaction, cooling to reaction system to room temperature, taking out the crystal substrate plated with film from the container for hydrothermal reaction, and washing with water and alcohol and drying to prepare the thorn-ball photochromic MoO3 thin film. The MoO3 thin film prepared by the invention can generate a good photochromic effect under a condition of a low power excitation light source, and the photochromic performance of the MoO3 thin film is improved.

Description

technical field

[0001] The invention relates to a kind of prickly spherical photochromic MoO 3 Preparation method of thin film, especially the preparation of prickly spherical photochromic MoO under the action of organic interfering agent formaldehyde 3 thin film method. Background technique

[0002] Some substances will change their color under the irradiation of light of a certain wavelength, and at the same time, they will restore their original color under the action of light, heat or avoiding light. The color of the substance is reversible under the action of light. The changing phenomenon is called photochromism.

[0003] Since TerMer first discovered dinitromethane potassium salt with photochromic properties in 1867, the research and application of photochromic materials have made great progress. Scientific researchers have developed a variety of organic and inorganic photochromic materials. Material. In recent years, photochromic materials have attracted more and...
