Using 2-hydroxy-4-methoxybenzophenone as carbon source and ethylenediamine as nitrogen source, an oil-soluble nitrogen doped carbon dots (CDs) with dual absorption of ultraviolet and short-wave blue light is synthesized by hydrothermal method. The composite lens material with ultraviolet light and short-wave blue light shielding effect is prepared by compounding CDs with polymethyl methacrylate. When the mass fraction of CDs is 1%, the average transmittance of the composite lens in the ultraviolet region is 0%, the average transmittance in the short-wave blue light region is 1.6%, and the absorption efficiency is 99.6%. It is a strong anti-ultraviolet-short-wave blue light material.

Key words: Oil-soluble carbon dots, UV absorption, Short-wave blue light absorption
