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.
[0013] 2) Preparation of chemical fluorescent solution: Take 50 ml of dibutyl phthalate in a beaker, add 10 ml of 30% hydrogen peroxide and 1 ml of tert-butanol as co-solvents,...

[0016] A method for preparing a carbon nanoparticle chemical fluorescent liquid, the specific steps of which are:
[0017] 1) Preparation of carbon nanoparticles: Weigh 0.50 g of tartaric acid and 0.20 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.

Embodiment 3
[0021] A method for preparing a carbon nanoparticle chemical fluorescent liquid, the specific steps of which are:
[0022] 1) Preparation of carbon nanoparticles: Weigh 0.50 g of fumaric acid and 0.20 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.
