Abstract

The invention provides dual-emission fluorescence carbon nanoparticles and a synthesis method and application thereof. According to the synthesis method of the dual-emission fluorescence carbon nanoparticles, o-phenylenediamine and ethanol amine serve as raw materials, and the dual-emission fluorescence carbon nanoparticles are prepared by adopting a solvothermal method. The dual-emission fluorescence carbon nanoparticles prepared by the invention generates dual emission fluorescence under stimulation of a single wavelength, and by adopting the dual emission wavelength, a proportional fluorescence detection system can be constructed to improve reliability of an analysis method.

Description

technical field [0001] The disclosure belongs to the technical field of nanomaterials, and relates to a double-emission fluorescent carbon nanoparticle and its synthesis method and application. Background technique [0002] The information disclosed in this Background section is only intended to increase the understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] Nitroaromatic explosives have the characteristics of great power, strong destructiveness, and low cost. They are more and more widely used in military and engineering construction, and are closer to life. However, due to its strong environmental pollution, and the frequent occurrence of terrorist attacks, criminal crimes and other incidents endangering public safety in the world in recent years, the detection of explosives has beco...
