The invention provides a printing ink using an inorganic nanometer material. The printing ink using the inorganic nanometer material adopts an organic solvent, and comprises at least one type of inorganic nanometer material and at least one type of fluorine-containing aromatic hydrocarbon organic solvent, wherein the structure of the fluorine-containing aromatic hydrocarbon organic solvent is shown in a formula V, namely (Rb')n'-(Rfb)n-(Rfa)m-(Ra')m'; Rfa is selected from partially or totally fluorated alkyl; in the formula V, Rfb is selected from partially and totally fluorated aromatic hydrocarbon or non-fluorated aromatic hydrocarbon; Ra' and Rb' are independently selected from H (hydrogen), aliphatic group with C1 to C30, aromatic group with C5 to C30, F (fluorine), Cl (chloride), Br (bromine) and I (iodine); the value ranges of m, n, m', and n' meet the requirements that m and n are respectively 0 or 1, and m and n are not simultaneously 0; m' and n' are respectively 0 or 1; whenn is 0, at least one of Ra' and Rb' is the aromatic group with C5 to C30; when m is 0, Rfb is selected from the partially or totally fluorated aromatic hydrocarbon.

Description

technical field [0001] The invention belongs to the technical field of electroluminescent diode display, and in particular relates to an inorganic nanometer material printing ink and a preparation method thereof. Background technique [0002] Quantum dot (QD), also known as nanocrystal, is a nanoparticle composed of II-VI or III-V elements. Quantum dots are zero-dimensional (zero-dimensional) nano-semiconductor materials, and the size of the three dimensions is not larger than twice the exciton Bohr radius of the corresponding semiconductor material. The performance of quantum dots is generally affected by the quantum confinement effect ( quantum confinement effect), surface effects and doping effects. The particle size of quantum dots is generally between 1 and 10 nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure with molecular characteristics, and can emit fluorescence after being excited. Q...
