[0021] Example of structure without iridescent structure color

[0022] The structure of the color without iridescent structure proposed by the present invention is composed of two media with different optical refractive indices. The structure composed of these two media has short-range correlation (also known as neighbor order) but does not have Long-range correlation (also called non-long-range order), and the optical correlation length of the structure is between 50 nanometers and 400 nanometers (including 50 nanometers and 400 nanometers). The properties of the color of this structure are: the color comes from the reflection of the incident light in space; in the absence of absorbing substances, the reflection and transmission colors are complementary; there is no iridescence phenomenon, and the color is uniform when viewed from different directions.

Abstract

The invention discloses a structure without iridescent structure color and a preparation method of the same to prepare pigments, schemochrome of which has no iridescent phenomenon. The technology scheme is as following: the preparation method includes arranging two mediums alternately which possess different optical refractive indexes, ensuring that the structure consisting of the two mediums has short range correlation rather than long range correlation, and controlling the optical correlation length in a range between 50 nm and 400 nm.

Description

Technical field [0001] The invention relates to a color structure and a preparation method thereof, in particular to a color structure without iridescent structure and a preparation method thereof. Background technique [0002] The colors of living beings in nature are derived from pigments or structures. The colors produced by pigments are called pigment colors, that is, chemical colors; the colors produced by structures are called structural colors, which are also called physical colors. The so-called structural color is the color produced by the reflection of the incident light in a specific wavelength and direction by the microstructure equivalent to the wavelength of light through interference, diffraction, scattering, and other means. Compared with pigment colors, structural colors have the advantages of high color saturation, constant structure and never fade, and environmental protection. [0003] However, a common feature of structural colors is iridescence. In some case...
