[0025] Preparation of monodisperse spherical colloidal photonic crystals: monodisperse colloidal crystal microspheres can be obtained by figure 1 The microfluidic device shown in was obtained. Typical preparation steps are as follows: select silica, polystyrene or polymethyl methacrylate nanoparticles with a particle size of 100nm-300nm and a polydispersity index of 0.01-0.1, and prepare a water phase with a mass fraction of 0.5%-30% Dispersions. Aspirate 250μl-750μl with syringe 1. Add oil-phase surfactant Span80 with a mass fraction of 0.01wt%-5wt% to dimethyl fluorinated silicone oil, and use syringe 2 to draw 5ml-15ml. Set the flow rate of the colloid solution to 1 μl / min-25 μl / min, and the flow rate of the silicone oil to 100 μl / min-500 μl / min. Simultaneously start the micro propulsion motor and propeller. When continuous emulsion droplets with equal spacing appear in the PTFE tube, extend the outlet end of the tube into a collection container filled with methyl silicon...

Abstract

The invention relates to an array type display component and a preparation method thereof, which realizes the self assembly of nano particles and the pattern step-by-step assembly of a display unit, is beneficial to realizing the large-area preparation of the display component and controlling the uniformity of a film and is easy for pattern design. Simultaneously, spherical colloid crystals are adopted, which is beneficial to decreasing a color bias generated by the change of the visual angle. The display component comprises a plurality of spherical colloid photon crystals with the same size and the diameter range of 10 microns to 1 millimeter, wherein each spherical colloid photon crystal is used as a pixel point or a pixel unit of the display component; a polymer is filled in hole gaps between the nano particles of the spherical colloid photon crystals, the back face of each spherical colloid photon crystal is connected with an electrode, the polymer generates an oxidation-reduction reaction at different voltage, a distance between the nano particles in the spherical colloid photon crystals is changed by the volume change generated when the polymer is oxidized and reduced, and the color of each spherical colloid photon crystal is accurately controlled.

Description

technical field [0001] The invention relates to a spherical colloidal photonic crystal material, especially a method for using it as a unit material in an array display device. Background technique [0002] Photonic crystals were first proposed in 1987 by Yablonovitch, a professor at the University of California, and John, a professor at the University of Toronto in Canada. It is formed by the orderly arrangement of two or more materials with different dielectric constants on the nanometer (micro) scale. In this material, a photonic band gap (photonicband gap or stop-band) similar to the semiconductor electronic band gap will appear, and the propagation of light with the same frequency as the photonic band gap will be suppressed by the photonic crystal. Photonic crystals can be used to construct low-threshold lasers, straight (sharp) angle waveguides, and other optical devices that are difficult to realize using conventional design methods. In addition, photonic crystals, ...
