| titleOfInvention | Quantum dot composite and preparation method and application thereof |
| abstract | The invention relates to a quantum dot composite and a preparation method and application thereof, the quantum dot composite takes quantum dots as cores, a silicon dioxide layer is coated outside the quantum dot composite, and m metal oxide layers and silicon dioxide layers or n metal oxide layers which are sequentially alternated are coated outside the silicon dioxide layer; compared with the uncoated quantum dots and the quantum dots coated by a single layer, the quantum dot composite has the advantage that the service life of the quantum dots is obviously prolonged on the premise of not influencing the luminous efficiency of the quantum dots in the process of mixing the quantum dot composite with glue. After the quantum dot composite is mixed with glue, the quantum yield of the quantum dot composite is still kept above 10%, and the quantum yield of the quantum dot only coated with a single layer of silicon dioxide is only about 1%. |
