| titleOfInvention | A kind of nitrogen sulfur doping fluorescent carbon quantum dot and its preparation method and application |
| abstract | The invention discloses a kind of nitrogen sulfur doping fluorescent carbon quantum dots and its preparation method and application, belong to the technical field of nano material preparation.The present invention is using taro, dilute sulfuric acid, water as raw material, microwave reaction is for a period of time, after natural cooling, water, stirring and dissolving is added to obtain brown suspension, it is filtered to remove after bulky grain insoluble matter and removes impurity by spin dialysis, fluorescent carbon quantum dot aqueous solution is obtained, obtains fluorescent carbon quantum dot after freeze-drying.Carbon source of the invention is from a wealth of sources, can largely prepare, and preparation process is simple, and preparation condition requirement is low, and gained nitrogen sulfur doping fluorescent carbon quantum dot quantum yield is higher, and can be applied to Cr in water body 3+ Detection. |
