摘要（英）：

The invention relates to a method of rapid preparation of a solid light-emitting carbon point having high fluorescence quantum yield. The method is against the situation that it is difficult to achieve light emitting of the solid light-emitting carbon point. Citric acid and N-beta-(aminoethyl)-gamma-aminopropyl trimethoxy silane are adopted as raw materials, the solid light-emitting carbon point is prepared through microwave-assisted hydrothermal synthesis, filtering, vacuum freeze drying, grinding and sieving. The preparation method is advanced in process, data is accurate and detailed, the prepared solid light-emitting carbon point is powder, the powder particle diameter is equal to or smaller than 7 nm, the fluorescence quantum yield is up to 65.8%, and the purity is up to 99.8%. The method of rapid preparation of the solid light-emitting carbon point having high fluorescence quantum yield is advanced and can be applied in solid fluorescent light-emitting devices.
