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] Unlike microscopic atoms, molecular clusters, and macroscopic bulk materials, inorganic nanoparticle materials are metastable intermediate substances between macroscopic solids and molecules. Since the ratio of the surface atoms to the total number of bulk atoms of inorganic nanoparticles increases sharply with the decrease of particle size, it shows strong volume effect, quantum effect, surface effect and macroscopic quantum tunneling effect. In addition, the size and shape of inorganic nanoparticle materials are controllable, and the physical and chemical properties are dependent on size and shape. Based on the above-mentioned series of characteristics, inorganic nanoparticle materials gradually show advantages over inorganic bulk ma...
