▎ 摘　　要

NOVELTY - The system has a main body provided with a femtosecond laser for generating a laser pulse. A terahertz emission device for receives pump pulses. A spectrum detection analysis device for obtaining terahertz time domain information and terahertz electric field information based on a fluorescence intensity of detected graphene quantum dot. A main body is provided with a chopper. The chopper receives the pump pulses emitted by a beam splitter. A stepping motor for adjusting and controlling a light delay device. USE - Graphene quantum dot fluorescence enhancement terahertz time-domain electric field detection system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene quantum dot fluorescence enhancement terahertz time-domain electric field detection system.
