Abstract

The invention relates to a preparation method of a metal photonic crystal material, belonging to the preparation field of inorganic nano materials. The method comprises the steps of: preparing a silicon dioxide reverse template material by taking colloid microspheres as a template material; preparing silicon dioxide inverse opal structure by a co-assembly method; then carrying out reduction reaction by using steam of dimethylaminoborane, wherein an alcohol solution of chloroauric acid and chloroplatinic acid are taken as a gold source and a platinum source; and finally synthesizing the metal photonic crystal material. The technical scheme in the invention is novel and reasonable in design, wide in application scope, simple in operation, easy to control in reaction, good in repeatability, free from pollution and good in safety. The prepared metal photonic crystal material is even in order within hundreds of microns, and is good in optical property.

Description

technical field [0001] The invention relates to a method for preparing a metal photonic crystal material, and belongs to the technical field of inorganic nanometer material preparation technology. Background technique [0002] Photonic crystal materials have the characteristics of photonic band gap, which can prevent the propagation of light in all directions, and have excellent optical properties. In particular, metal photonic crystal materials have been proved by simulation methods to have a complete photonic band gap, which is a new type of material to replace semiconductor materials. The existence of the photonic bandgap makes it possible to realize the spontaneous propagation of photons at specific frequencies. This ability to control the propagation of light in three-dimensional ordered photonic crystals has broad applications in quantum optics and its devices. For example, black-body radiation can be corrected to confine light to a certain area, which enables the re...
