Abstract
A quantum dot, a light-emitting module and a synthesis method of the quantum dot are provided. The quantum dot includes a seed crystal and a quantum dot material layer grown on the surface of the seed crystal. In the quantum dot, the quantum dot material layer is grown on the surface of the seed crystal, the quantum dot material is attached to the seed crystal for oriented growth, thereby achieving low lattice stress during quantum dot growth, and allowing the quantum dot to have few growth defects and high performance.
Claims20
A quantum dot, comprising:
- a seed crystal;
- and
- a quantum dot material layer grown on the surface of the seed crystal.
A light-emitting module, comprising:
- a quantum dot layer, wherein the quantum dot layer comprises a quantum dot comprising a seed crystal and a quantum dot material layer grown on the surface of the seed crystal.
A method for synthesizing quantum dot, comprising following steps:
- dispersing the seed crystal in a first quantum dot precursor;
- providing a second quantum dot precursor, mixing and reacting the first quantum dot precursor with the seed crystal dispersed therein and the second quantum dot precursor to have the first quantum dot precursor and the second quantum dot precursor to grow on the surface of the seed crystal to form a quantum dot material layer, and obtaining the quantum dot.
