▎ 摘　　要

NOVELTY - Method for generating white light using white light-emitting quantum dots (WL-GQD), involves mixing a polycyclic aromatic hydrocarbon as a carbon precursor and a heteroatoms co-doping compound in deionized water to obtain a mixture, where the polycyclic aromatic hydrocarbon is naphthalene and the heteroatoms co-doping compound is thiourea, fabricating heteroatoms co-doped graphene quantum dots by performing thermal procedure on the mixture, obtaining WL-GQD by drying residue of the fabricated heteroatoms co-doped graphene quantum dots, and generating white light using obtained WL-GQD. USE - Method for generating white light using white light-emitting quantum dots. ADVANTAGE - The WL-GQD is prepared using environmentally-friendly components, such as polycyclic aromatic hydrocarbon and heteroatoms co-doping compound as base material. The WL-GQD is a single carbon quantum dots (CQD) which makes mass production easy and cost-effective.
