Abstract

The invention discloses a preparation method of yttrium vanadate three-dimensional inverse opal photonic crystal. The method comprises the steps of (1) preparing polymethyl methacrylate nanospheres; (2) growing an opal structure photonic crystal; (3) preparing an inverse opal photonic crystal precursor solution; and (4) sintering the inverse opal photonic crystal. Compared with a laser etching method, the method has the advantages that the prepared photonic crystal is uniform in structure, accurate in photonic band gap and low in preparation cost, and the method can be used for massive production of the photonic crystal.

Description

technical field [0001] The invention belongs to the technical field of photonic crystals, and in particular relates to a method for preparing a three-dimensional inverse opal photonic crystal of yttrium vanadate. Background technique [0002] Photonic crystals refer to artificial periodic dielectric structures with photonic bandgap properties. According to the geometric characteristics of photonic crystals for light modulation, they can be divided into: one-dimensional photonic crystals, two-dimensional photonic crystals, and three-dimensional photonic crystals. Since three-dimensional photonic crystals can modulate photons in the entire space, photonic crystals have been widely used in optical fibers, zero-threshold lasers, integrated optical circuits, and lossless mirrors in recent years. As a dielectric material, yttrium vanadate has high refractive index, good mechanical and physical properties, and is an ideal material for photonic crystals. [0003] At present, photo...
