Problems solved by technology

This fluorescent system has several disadvantages: firstly, the price of materials for dyeing many fluorescent dyes is relatively high, such as: rubrene is several hundred yuan per gram; secondly, fluorescent dyes have great environmental pollution, such as: rhodamine B has Strong carcinogenic effect, potential environmental problems; the third is short luminous time
Traditional quantum dots mainly contain heavy metals such as cadmium sulfide and cadmium selenide, and have good fluorescence performance, but their toxicity limits their application.

Embodiment 1

[0011] A method for preparing a carbon nanoparticle chemical fluorescent liquid, the specific steps of which are:

[0012] 1) Preparation of carbon nanoparticles: Weigh 0.50 g of citric acid and 0.10 g of ammonium oxalate with a balance, grind them into a beaker, add 20 ml of ethylene glycol to dissolve into a colorless and transparent solution. Transfer the solution to a reaction kettle, tighten the lid of the kettle, place in a constant temperature drying oven at 180°C and heat for 3 hours, take out the reaction kettle, and let it cool down to room temperature naturally. The resulting reaction product was a brownish yellow carbon nanoparticle solution, which was then transferred to a beaker and dried in a vacuum oven at 60°C to obtain brown solid carbon nanoparticles, which were kept for future use.

Abstract

The invention discloses a preparation method of a carbon nanoparticle chemiluminescent liquid. According to the method, fluorescent carbon nanoparticles are taken as a luminous agent, and dibutyl phthalate is taken as a solvent and hydrogen peroxide and diphenyl oxalate are taken as exciting materials by virtue of the fluorescent carbon nanoparticles; hydrogen peroxide and diphenyl oxalate are subjected to chemical reaction to generate high-energy materials for exciting the carbon nanoparticles to generate chemical fluorescence; dibutyl phthalate, 30% hydrogen peroxide and a small quantity of tertiary butanol used as a cosolvent are added into a beaker in sequence to prepare a colorless transparent solution; dibutyl phthalate, the carbon nanoparticles, diphenyl oxalate and sodium salicylate are added into the beaker and are heated and dissolved to prepare a solution; the two solutions are mixed at a ratio of 1:1 to obtain the carbon nanoparticle fluorescent liquid, and the chemical fluorescence can be generated after the two solutions with the same volume are mixed. The chemiluminescent liquid synthesized by adopting the method is high in luminous brightness, long in duration time, free of cancerogenic substances and heavy metal pollution, low in preparation cost and easy for large-scale industrial production.

Description

technical field [0001] The invention relates to a method for preparing a carbon nanoparticle chemical fluorescent liquid. Background technique [0002] Substances will emit bright light in the state of combustion or high temperature, providing illumination for people's life and various activities. This kind of light requires high temperature, which is called high temperature luminescence. Fluorescent dyes can also emit light when they are excited by ultraviolet light or chemical excitation at low temperature. This light does not require high temperature, which is called fluorescence or luminescence. In some specific occasions, such as: no power supply, no fuel, special explosion-proof environment, the use of high-temperature light sources is not allowed to avoid danger, and high-temperature light sources are restricted. In order to overcome this difficulty, a new type of chemical light source that is easy to carry and has a long luminous life has been developed, which produ...
