Abstract

The invention discloses a method for improving color brightness of non-rainbow structural color by introducing black nanoparticles and graphene quantum dots into a disordered optical structure. The method comprises the following steps of firstly, mixing monodisperse colloidal particles, black nanoparticles and graphene quantum points of different particle sizes according to a certain ratio, and uniformly dispersing into water, so as to form an emulsion; placing the emulsion onto a substrate by drip coating, rotary coating, soaking coating, lifting, spraying, ink jet printing and the like, anddrying, so as to form a non-rainbow structural color material with high structural color brightness. The non-rainbow structural color material with high structural color brightness obtained by the method has important application prospect in the fields of chemical/biological sensors, reflective monitors, pigments, decorative pattern layers and the like. The method has the advantages that the photoluminescence of the graphene quantum dots is effectively regulated, controlled and enhanced; the graphene quantum dots are promoted to be applied to optical devices.

Description

technical field [0001] The invention relates to a method for improving the color brightness of structural colors, in particular to a patterned preparation method for improving the color brightness of non-rainbow structural colors by using black nanoparticles and photoluminescent quantum dots to work together, and belongs to the technical field of display material preparation. Background technique [0002] Some birds in nature, such as spotted-throated umbrellabirds and macaws, have very brightly colored feathers, and these bright colors have attracted widespread attention from scientists. Studies have found that, unlike the colors of traditional dyes and pigments, such colors are caused by the irregular arrangement of submicron-scale keratin on the microscopic scale. Such colors caused by special optical structures are called structural colors. Inspired by the design of such special optical structures in nature, scientists have synthesized a large number of non-iridescent s...
