[0031] The invention also discloses another method for preparing an anti-blue light film, which includes the following steps: dissolving epoxy resin and ethylenediamine in methanol solution, adding the methanol solution of anti-quenching carbon quantum dot solid composite and heating to Methanol volatilization prepared CDs1 / epoxy resin anti-blue light polymerized film;
[0032] In this embodiment, 2-3g of epoxy resin, 90-110μL of ethylenediamine, 4-6mL of methanol solution, 0.1-3mL of methanol solution of anti-quenching carbon quantum dot solid composite; The methanol solution concentration of the solid complex is 15-25mg / mL; the heating temperature is 60-80°C.
[0033] CDs1 of the present invention is dispersed state in water, surface charge is low, fluorescence wavelength is short (for blue-green light) and fluorescence intensity is also low; CDs1 is dispersed in methanol and is aggregated state, surface charge is abundant, fluorescence is yellow-green, and quantum efficienc...

[0036] Preparation of anti-quenching carbon quantum dot solid composite: add rutin into NaOH solution, and react in a 500mL reactor at 180°C for 48h. The water was evaporated to dryness with a rotary evaporator, and the obtained solid was dissolved in an organic solvent and then separated by column chromatography. The highly polar one was an anti-quenching carbon quantum dot solid complex (CDs1).
[0037] Preparation of anti-blue light film: Add 2.6g epoxy resin and 100μL ethylenediamine to 5mL methanol solution to dissolve, then add 0.5mL methanol solution (20mg / mL) of anti-quenching carbon quantum dot solid complex, and dissolve the mixture Heated at 70°C for 4h to volatilize methanol, transferred to a mold, and cured in an oven at 40°C for one week to obtain a polymer film of anti-quenching carbon quantum dot solid composite and epoxy resin (CDs1 / Epoxide resin (a) ).
