Carbon quantum dots C QDs are prepared by patented technology. The size is generally less than 10 nm. It is mainly composed of SP2 hybrid conjugated structure. The surface contains abundant oxygen-containing or other heteroatom organic molecular light-emitting groups, and it does not contain toxic heavy metal elements. Safe and environmentally friendly, it can be used in fields such as display, device, tracer, biomedicine, catalysis, etc.
