Description
Technical field
The present invention relates to quantum dot composite material fields, compound in particular to a kind of quantum dot composition, quantum dot
Material, preparation method and application.
Background technology
Quantum dot, and can be described as nanocrystalline, it is a kind of nano particle being made of II-VI group or iii-v element.Amount
The grain size of son point is typically in the range of between 1~10nm, and since electrons and holes are by quantum confinement, continuous band structure becomes to have
The discrete energy level structure of molecular characterization can emit fluorescence after being excited.Based on quantum effect, quantum dot is in solar cell, hair
The fields such as optical device and optical bio label are with a wide range of applications.
Quantum dot has exciting light spectrum width and continuously distributed, and emission spectrum is narrow and symmetrical, Color tunable, photochemical stable
Property high, the superior fluorescent characteristic such as fluorescence lifetime length.By the shape, structure and size that control quantum dot, so that it may with easily
Its energy gap width, exciton are adjusted (in semiconductor, if an electronics is gone on from full valence to empty conduction band, in valence
With one hole of interior generation, and an electronics is generated in conduction band, to form an electron-hole pair.Hole is positively charged, electricity
Subband negative electricity, the coulomb adelphotaxy between them can be spatially bound together under certain conditions, such shape
At complex be known as exciton) (bands of a spectrum of organic compound are often because of substituent group for the energy blue shift of the size of binding energy and exciton
Change with quantity of solvent makes maximum absorption wavelength and absorption intensity change.It is known as when maximum wavelength is moved to shortwave direction
Blue shift;Blue shift refers to the frequency of the electromagnetic wave that the object of positive observer's movement is scattered on spectrum line to the direction at blue end
It is mobile, it is meant that wavelength reduces.With the reduction of particle size color to blue light direction move) etc. electronic states.Therefore, can lead to
The size for crossing control quantum dot obtains the arbitrarily desired color in visible light region, and can be obtained by the size of control half-peak breadth
The monochromatic light of pure color can increase substantially colour gamut and color saturation for display field.
Between being typically in the range of 1~10nm due to the grain size of quantum dot, there is very big specific surface area, surface phase atomicity
Increase, the coordination for resulting in surface atom is insufficient, unsaturated bond and dangling bond (i.e. the unpaired electronics of crystalline surface) increase, and makes
These surface atoms have high activity, extremely unstable, it is easy to be combined with other atoms.Therefore, general quantum dot surface needs
Suitable ligand is selected to be coordinated with the metal of quantum dot surface, the type of ligand has certainly the efficiency and stability of quantum dot
Qualitatively influence.With the development and optimization of quantum dot synthetic technology, the efficiency and stability of quantum dot have reached industrialization
Level.But the unique skin effect of quantum dot also determines that its sensibility to aqueous vapor and oxygen, aqueous vapor and oxygen can be broken
The ligand of bad quantum dot surface reduces the efficiency of quantum dot.Quantum dot size is smaller, and specific surface area is bigger, to aqueous vapor and oxygen
Sensibility it is higher.
With the maturation of quanta point material, the application of quanta point material is more and more wider, especially in display field.But it measures
Son point material cannot be used alone, it is necessary to be dispersed in macromolecule matrix.In view of the characteristic of quantum dot itself, macromolecule matrix
There must be following characteristic:(1) there is preferable compatibility with quanta point material, the luminous efficiency of quantum dot can be kept well
(2) there is preferable barrier property to aqueous vapor and oxygen;It (3) can be by liquid curing at solid-state under the action of light or heat.
Macromolecule matrix about dispersion quantum dot has many reports, can be summarized as following a few classes:(1) to quantum dot surface
It carries out silicone-modified, selects organosilicon material as macromolecule matrix, be mainly used for the encapsulation in situ of LED chip.Organosilicon
Material has extraordinary thermal stability and optical stability, still, due to the high-flexibility of organosilicon material silicon oxygen bond and big
Bond angle, it is poor to the barrier property of aqueous vapor and oxygen.Under conditions of high temperature and blue light illumination, quanta point material be easy by
The destruction of aqueous vapor and oxygen and fail.(2) it is made using porous material absorption quantum dot or by quantum dot epoxy resin cladding
Microballoon.Epoxy resin is poor with the compatibility of quantum dot due to higher polarity, and hair is easy under conditions of high temperature illumination
Huang influences quantum dot luminous efficiency.(3) select acrylate monomer or polyacrylate as macromolecule matrix.Acrylate
There are preferable compatibility, quantum dot that can preferably be dispersed in acrylate with quantum dot.But acrylate is to aqueous vapor and oxygen
The barrier property of gas is poor.(4) phase separation structure is formed, disperses quantum dot using hydrophobic systems (acrylate), outer layer is used
Hydrophilic system (epoxy resin) starvation, is macroscopically forming phase separation structure.Nothing between acrylic resin and epoxy resin
Chemical bond and effect, there are certain defects for long-term chemical durability aspect.
Therefore, it is still necessary to the application of quantum dot in the prior art is improved, to improve the luminous efficiency of quantum dot
And stability.
