product name


Chinese name: WS2 single layer quantum dot solution


English name: Single layer WS2 quantum dots


 


Nature


Concentration: 0.5 mg/ml


Particle size: less than 10nm


Solvent: water


Stabilizer: lithium hydroxide


PH: 8-9


Remarks: This quantum dot does not emit light


 


Preparation


WS2 quantum dots are prepared by a lithium intercalation method. In the later stage of preparation, large-diameter molybdenum disulfide is removed by centrifugation. Quantum dots are the main component, and some nanosheets may remain. The quantum dots prepared by the intercalation method do not emit light, but because they have a large number of defects and specific surface area, they are ideal materials for electrochemical applications.


 


Application field


Sensing detection, optoelectronic devices, medical field, lubricating additives, etc.


 


Storage Conditions


Please keep the tungsten disulfide quantum dot solution at 4℃ under inert gas protection, and use it within one week after opening. The maximum time is 1 month.

Tungsten disulfide quantum dot powder should be stored in a dry and dark sealed manner at room temperature. The maximum time is 3 months.
