Embodiment Construction

[0021] Examples of structures without iridescent structural colors

[0022] The structure of the non-iridescent structural color proposed by the present invention is: it is formed by two kinds of media with different optical refractive indices, and the structure composed of these two media has short-range correlation (also known as neighbor order) but does not have Long-range correlation (also known as no 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 this structural color 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 iridescent 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 non-iridescent structural color structure and a preparation method thereof. Background technique [0002] The color of organisms in nature comes from pigment or structure. The color produced by pigment is called pigment color, that is, chemical color; the color produced by structure is called structural color, also known as physical color. The so-called structural color is the color produced by the reflection of the incident light at a specific wavelength and in a specific direction by a microstructure equivalent to the wavelength of light through interference, diffraction, scattering, etc. Compared with pigmented colors, structural colors have the advantages of high color saturation, unchanged structure, never fading, and environmental protection. [0003] However, a common feature of structural colors is the phenomenon of iridescence. In some cases, havi...
