[0065] In the preparation process of the quantum dot material, in order to prevent oxidation, it needs to be carried out under the protection of an inert environment (such as nitrogen), and an anhydrous and oxygen-free ultra-dry solvent can be used. The quantum dots can be washed and dissolved, and then the quantum dots and the quantum dot ligand structure are mixed and reacted for a period of time, so that the quantum dots and the groups (such as thiol) in the quantum dot ligand structure are connected through coordination bonds, and the reaction lasts for a period of time. After a period of time, quantum dot materials can be obtained through processes such as sedimentation, centrifugation, washing and separation. For example, when the quantum dot ligand structure is a mercaptoazobenzene compound, the ordinary quantum dot solvent can be removed by a rotary evaporator, and re-dissolved with 5mL chloroform to obtain a quantum dot solution, and added to a 20mL reflux bottle equip...
