Background technique
With the continuous development of display technology, people are also higher and higher to the display quality requirement of display device.Quantum dot
(Quantum Dot, abbreviation QDs) is partly led what conduction band electron, valence band hole and exciton were held on three direction in spaces
Body nanostructure, this constraint can be attributed to electrostatic potential (by external electrode, adulterating, strain, impurity generates), two kinds of differences
The interface (such as: from group quantum dot) of semiconductor material, the surface of semiconductor (such as: semiconductor nanocrystal), or
The combination of the above three.Quantum dot has the quantized power spectrum of separation, and corresponding wave function is spatially positioned at quantum dot
In, but extend in several lattice periods.One quantum dot has the electronics, hole or sky of a small amount of (1-100) integer
Cave electronics pair, the i.e. electricity of its band are the integral multiples of former charge.
And quantum dot (Quantum Dots, abbreviation QDs) be usually the spherical shape being made of II-VI or iii-v element or
Spherical Semiconductor Nanometer Particles, partial size is generally at several nanometers between tens nanometer.Be less than due to the particle size of QDs or
Person can generate quantum confined effect close to the Exciton Bohr Radius of corresponding body material, and level structure is quasi-continuous from body material
The discrete topology for becoming quanta point material causes QDs to show the luminous performance of special stimulated radiation.With the size of QDs
Reduction, the increase of energy level band gap, energy required for corresponding QDs is excited and QDs return to the energy of ground state releasing after being excited
It is all corresponding to increase, the excitation of QDs and " blue shift " phenomenon of fluorescence spectrum are shown as, by controlling the size of QDs, it is made to shine
Spectrum can cover entire visible light region.The size for such as pounding cadmium (CdSe) is decreased to 2.0nm, emission wavelength from 6.6nm
From red light region 635nm " blue shift " to the 460nm of blue region.
It is so-called colored filter (Color Filter) material that general liquid crystal display, which is used to generate the material of color, at present
Material, principle is that the white light of mixing is filtered into each color of light in the way of light absorption, the most luminous energy of this mode
Amount can be all filtered, therefore quantum efficiency is low.Quantum dot (Quantum Dots, abbreviation QDs) material, which refers to, utilizes material
Energy rank quantum effect, continuous band structure become the discrete energy stage structure with molecular characterization, this material can absorb higher energy
The photon of amount or shorter wavelength come and by electronics electricity hole to excitation to excitation state, later relaxation and it is compound (Recombination)
And release photon (Emission), that is, not the mode of traditional filtering light by the photon of high-energy (such as: ultraviolet light or indigo plant
Light) it is changed into the mode of low-energy light to generate color, therefore quantum efficiency is higher.
The quantum dot liquid crystal display of market today is the white light backlight that traditional blue light is added to yellow fluorescent powder mostly
It changes into white to generate in a manner of high-energy light (such as: blue light or ultraviolet light) Lai Jifa quanta point material (such as: quantum dot film)
Light backlight, but still there is colored filter (Color Filter) material, therefore there is no improve in liquid crystal display
Substantially low efficiency the problem of.
