Embodiment 1

[0066] A preparation method of composite nanoparticles, comprising the following steps:

[0067] S11.C 60 (OH) 36 is prepared as follows:

[0068] 10 mL (20 mmol / ml) of NaOH solution was added to the flask, and 0.5 mL (10%) of tetrabutylammonium hydroxide TBAH solution was added dropwise. With vigorous stirring, 12 mL containing 20 mg C was added dropwise 60 toluene solution, and then add dropwise 1ml (30%) of H 2 O 2 solution, and continue to stir the reaction for 2 hours. After standing, the reaction mixture was divided into two layers, the upper layer was a colorless organic phase, and the lower layer was a brown-black aqueous phase. Separation and separation, filtration to remove insoluble matter in the water phase, to obtain a brown-black solution. Methanol was added to precipitate a precipitate (soil yellow), and the methanol was removed by centrifugation; water was added to dissolve the precipitate, and then methanol was added to precipitate it, and this was repe...

Description

technical field [0001] The invention belongs to the technical field of composite nanomaterials, and in particular relates to a composite nanoparticle and its preparation method and application. Background technique [0002] In the field of new display technology in the future, printing technology is expected to realize the industrial revolution of display. Display components based on quantum dot light-emitting diodes (QLED) and organic light-emitting diodes (OLED) are the subject of technical research. [0003] Printing and coating are a necessary means to realize large-area display technology. Some problems encountered when preparing large-area red, green and blue components (pixels) through printing and coating technology, such as: pixels, especially It is a blue pixel with low efficiency and high lighting voltage. At present, the analysis of these technical problems mainly takes the red, green and blue devices prepared separately by the solution method in the laboratory ...
