Example Embodiment
[0038]Example 1:
[0039]1) Weigh 100mg of safranine T and dissolve it in 20mL 0.5M sodium hydroxide solution, and ultrasound for 10 minutes to completely dissolve safranine T; transfer the safranine T solution to an autoclave lined with 50mL PTFE, and After heating at 200°C for 5 hours, the CDs solution was obtained and stored in a refrigerator at 4°C.
[0040]2) Take different volumes (100 μL, 500 μL, 1000 μL, 2000 μL, 3000 μL, 3500 μL) of the CDs solution prepared in step 1) and 2 g of boric acid, add them to 40 mL of secondary water, and sonicate for 10 minutes to mix well. The mouth of the beaker is sealed with tin foil to prevent the moisture from evaporating too quickly.
[0041]3) Place the mixed solution of CDs and boric acid in step 2) in an oven at 180°C for 5 hours and then cool to room temperature.
[0042]4) Grind the sample prepared in step 3) into powder, and finally get CDs / B2O3The compound powder is stored in a desiccator.
