Resumen de: WO2023279624A1

Disclosed in the present invention are enhanced yellow light carbon dots, and a preparation method therefor and the use thereof, which belong to the technical field of manufacturing functional light-emitting carbon materials. In the present invention, citric acid and urea are dissolved in N,N-dimethylformamide, and reacted at 150-180°C for 4-8 h to obtain a carbonized mixture; the carbonized mixture is separated and purified by means of column chromatography and by using an eluent, which is prepared according to the volume ratio of dichloromethane to methanol from the largest to the smallest; a solution, which is obtained by means of elution when the volume ratio of dichloromethane to methanol is 1 : 1-2, is collected, subjected to rotary evaporation to remove a solvent, and then dried to obtain yellow carbon dots. By means of the present invention, yellow light carbon dots having a fluorescence intensity enhanced with increasing temperature are synthesized, such that the problems of the occurrence of a false positive signal and thus the temperature being not accurately determined, which are caused by the easy influence of the environment to a common quenching-type nano thermometer, are avoided. The yellow light carbon dots prepared in the present invention have an application value in the fields such as temperature determination, biological imaging and photoelectric equipments.
