Abstract

The invention discloses a nickel photonic crystal with an inverse opal structure and a preparation method thereof, and relates to a photo-electronic material and the preparation method thereof. The photonic crystal comprises the material composition nickel, and has the inverse opal structure. The photonic crystal with the inverse opal structure is prepared by utilizing a three-dimensional colloidal crystal template by the following steps of: A, preparing the mixed solution of 2.13mol / L NiSO4, 0.35mol / L Ni(Cl)2 and 0.43mol / L H3BO3, and placing the mixed solution into a second container; B, placing the three-dimensional colloidal crystal template prepared in a fourth step into the mixed solution prepared in the step A, and performing electrochemical deposition on the metal nickel in the three-dimensional colloidal crystal template by using a three-electrode system; and C, impregnating a sample obtained in the step B with a toluene solvent until the three-dimensional colloidal crystal template is completely dissolved, taking the sample out and washing the sample to obtain the nickel photonic crystal with the inverse opal structure. The preparation method is simple and convenient, and is applied in the fields of photonic devices, surface plasmas, optical communication, solar batteries, catalytic materials, battery electrodes and the like.
