Embodiment 1

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

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

[0068] Add 10 mL (20 mmol / ml) of NaOH solution to the flask, and dropwise add 0.5 mL (10%) tetrabutylammonium hydroxide TBAH solution. With vigorous stirring, 12 mL containing 20 mg C 60 Toluene solution, then dropwise added 1ml (30%) of H 2 O 2 The solution was stirred for 2 hours. After standing still, 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. Liquid separation, filtration to remove insoluble matter in the water phase, to obtain a brown-black solution. Add methanol to precipitate a precipitate (khaki), and centrifuge to remove methanol; add water to dissolve the precipitate, then add methanol to precipitate it, and repeat this 3-4 times until NaOH and TBAH are completely washed away. The resulting precipitate was vacuum-dr...

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 ...
