Abstract
Provided are a quantum dot material, a preparation method and use thereof. The quantum material includes a quantum dot, and a first cladding layer and a second cladding clad outside of the quantum dot, wherein the first cladding layer is located between the quantum dot and the second cladding layer. The quantum dot material provided herein has good water and oxygen barrier properties and good stability.
Claims15
A preparation method for a quantum dot material, comprising:
- (1) mixing a quantum dot solution and a precursor material of a first cladding layer, cladding by a reaction to obtain a quantum dot material with the first cladding layer;
- and
- (2) depositing a second cladding layer outside the quantum dot material with the first cladding layer by an atomic layer deposition method to obtain the quantum dot material;
- wherein the quantum dot solution has a concentration of 1 mg/mL to 200 mg/mL, the precursor material is added in an amount of 0.1% to 10%;
- the quantum dot material, comprising a quantum dot, and a first cladding layer and a second cladding layer clad outside of the quantum dot;
- wherein the first cladding layer is located between the quantum dot and the second cladding layer.
