Due to its excellent fluorescence, biocompatibility, easy modification and simple preparation process, carbon based nano luminescent materials have great potential in the fields of biomarkers, medical diagnosis and treatment, chemical / biosensors and photoelectric devices Although the preparation and application of carbon nanomaterials have made a lot of important progress in recent years, there are still many problems to be solved in the regulation of their luminescent properties and practical applications In view of these problems, the researchers of Ningbo Institute of materials technology and engineering of Chinese Academy of sciences have carried out systematic research and made a series of progress The researchers of trichromatic carbon based fluorescent nanomaterials and their applications have realized the preparation of trichromatic carbon based fluorescent nanomaterials that can be excited by a single wavelength for the first time, and preliminarily investigated their potential applications in flexible panchromatic light-emitting films and polychromatic biological imaging (angew Chem Int ed 2015, 54, 5360-5363), which can cover the whole visible light region, has realized the preparation of all wavelength emission carbon based fluorescent nanomaterials, and investigated their potential applications in the field of cell polychromatic labeling and multimode chemical sensing (adv mater 2015, 27, 7782-7787); recently, researchers have also made progress in the preparation of long wave long emission carbon based fluorescent nanomaterials with high fluorescence quantum efficiency, realizing the regulation from efficient red light to near-infrared emission (chem Mater 2016, 28, 8659 − 8668; nanoscale, 2016, 8, 17350-17356) and its application in biomedical field has realized two-photon and near-infrared imaging and near-infrared photothermal treatment of tumor cells In addition to the high-efficiency red emission carbon based fluorescent nanomaterials and their applications, they also reported the triple emission characteristics (up, down conversion fluorescence and phosphorescence) of these materials for the first time through the composite strategy, and applied them to the field of advanced anti-counterfeiting The research results were published in the form of "VIP" and cover paper in German Journal of Applied Chemistry (angel Chem Int ed 2016, 55, 7231-7235)。 Triple emission carbon based fluorescent nanomaterials and their applications
