Preparation method of carbon-based nano particle multi-color fluorescent ink

Abstract

The invention relates to a preparation method of carbon-based nano particle multi-color fluorescent ink, and reates to a preparation method of fluorescent ink. According to the method, carbon-based nano particles are adopted as illuminants, a formula is regulated to enhancing illumination through carbon nano particles, the illumination color is changed through regulating the types of carbon nano points, and the carbon-based nano particle multi-color fluorescent ink is heated. The preparation method comprises the following steps: adding nano silicon dioxide, nano starch, nano protein powder, apreservative, polyethylene glycol 1500 and water into the fluorescent carbon nano particles, carrying out uniform ultrasonic stirring, and keeping the temperature at 60 DEG C for 2 hours to obtain thecarbon-based nano particle multi-color fluorescent ink. The fluorescent ink provided by the invention has wide raw material sources, simple synthesis method, simple required equipment and fast preparation speed; the obtained multi-color fluorescent ink is green and environmentally friendly and is convenient to carry and store; solid luminescence of fluorescent mark is realized; and the multi-color fluorescent ink is a good tool for advertisement, entertainment and teaching.

Description

technical field [0001] The invention relates to a preparation method of fluorescent ink, in particular to a preparation method of carbon-based nano particle multi-color fluorescent ink. Background technique [0002] Fluorescent carbon nanoparticles are new materials in the field of luminescence. The nanomaterials with a particle size of less than 10nm and centered on carbon particles are also called carbon nanoparticles. Because its surface is covered with active groups, such as amino, carboxyl, hydroxyl, carbonyl and other active groups, its aqueous solution has excellent photoluminescent properties, such as strong and stable fluorescence, adjustable excitation and emission wavelengths, and excellent Fluorescent emission in the visible light region, etc., carbon nanoparticles are also called fluorescent carbon nanoparticles. Fluorescent carbon nanoparticles are widely used in a wide range of applications, such as: fluorescent cell labeling, tumor cell live imaging, metal i...
