| abstract |
The invention provides a quantum dot ink, comprising: oil-soluble quantum dot 0.1-20wt%, long carbon chain solvent 50-95wt%, additive 0-45wt%; wherein, the long carbon chain solvent is selected from C13-C16 saturated alkanes At least one of alcohols and C10-C12 enols. The quantum dot ink provided by the invention solves the problems of difficult removal of solvents and additives and poor dispersibility of quantum dots in current inkjet printing quantum dot inks. The invention has important significance for the application of quantum dots in the field of electroluminescence. |
