Description

technical field

[0001] The present invention relates to the technical field of polymer materials, and furthermore, relates to a series of high-fluorescence-intensity blue-light fluorescent polymers, fluorescent powders, fluorescent fibers, ultraviolet-to-blue-light resins and their preparation methods and applications. Background technique

[0002] Fluorescence is photoluminescence, which means that after a fluorescent substance absorbs external high-energy light radiation (such as ultraviolet, X-ray, and short-wavelength sunlight), it causes an internal electronic energy level transition and re-releases low-energy long-wave light. Due to the difference in wavelength, fluorescence has important application prospects in mineralogy, gemology, medicine, chemical sensing, fluorescent labeling, dyes, and biological detection. Fluorescent substances can be broadly divided into inorganic and organic fluorescent substances. Compared with inorganic fluorescent agents, organic fluores...
