Problems solved by technology

However, as a superior luminescent material, quantum dots still have many basic problems that have not been resolved. In particular, the stability of quantum dots has plagued many research units and has become one of the bottlenecks restricting the development of quantum dots.
Furthermore, the stability of quantum dots in other application fields, such as solar cells, biomarkers, and environmental pollution treatment, is also a great challenge.

Abstract

The present invention discloses a quantum dot material comprising an optical core, an inorganic ligand layer which includes at least one SiOx material wrapped on the surface of the optical core, and awater-vapor barring layer wrapped on the surface of the inorganic ligand layer. The abovementioned water-vapor barring layer is formed by stacking a plurality of stacked structures including at leastone metal oxide in an irregular arrangement. In addition, a manufacturing method and application of the quantum dot material are also disclosed by the present invention.

Description

technical field [0001] The invention relates to a composite quantum dot material, a preparation method of the composite quantum dot material and a display device thereof, in particular to a composite quantum dot material capable of improving the stability and luminous efficiency of quantum dots, and a preparation method of the composite quantum dot material and its display device. Background technique [0002] Since quantum dots were produced, they have aroused widespread interest in the scientific and industrial circles due to their excellent photoelectric properties. Compared with traditional fluorescent materials, the luminescent properties of quantum dots have more advantages such as narrow half-peak width, small particles, no scattering loss, and adjustable spectrum with size. Application prospects. [0003] All units have invested a lot of time and labor costs in the research of quantum dot materials, so that the photoelectric performance of quantum dots has been con...
