High-stability carbon nanometer fluorescence dye

Abstract

The invention provides a high-stability carbon nanometer fluorescence dye. The high-stability carbon nanometer fluorescence dye is coated on the surface of a conventional luminescent material, can be used for changing a luminescent spectrum and comprises a carbon nano-dot fluorescent material, a thinning agent, a binding agent and a fluorescent dyeing matter. The high-stability carbon nanometer fluorescence dye is characterized in that the carbon nano-dot fluorescent material is mixed with the thinning agent to form a fluorescent solution containing the carbon nano-dot fluorescent material; the fluorescent solution is uniformly mixed with the binding agent to form a fluorescent binding agent; and the fluorescent binding agent is combined with the fluorescent material. The high-stability carbon nanometer fluorescence dye provided by the invention has the characteristics of transparency, stability, no toxicity, environmental protection, low cost, simplicity in use and the like. The high-stability carbon nanometer fluorescence dye can be widely applied to the fields such as color long afterglow, light emitting display, light conversion agents, anti-fake fluorescent materials and various coatings.

Description

technical field

[0001] The invention belongs to the preparation technology of luminescent material in the field of solid luminescence. Background technique

[0002] Most of the fluorescent dyes used in existing luminescent materials are mainly organic materials. Due to their poor temperature resistance, poor light fastness, and fear of humidity, their application range has been limited for a long time, such as in the field of luminous lighting, outdoor advertising, and luminous indicators. Signage and other fields cannot be applied on a large scale. Such as the existing long-lasting luminescent materials, green and blue-green have good brightness and long life, while yellow and orange have poor brightness and life. Yellow and red are mainly dyed with organic dyes or sulfide rare earth materials, and they have not been used on a large scale. The existing fluorescent pigments have better stability than fluorescent dyes, but they are opaque, large in size and slightly toxic, ...
