(element) when being reduced in size to equal to or less than intrinsic bohr exciton radii, the band gap of the unit increases.Therefore, when entering
When penetrating the wavelength of light over the qds has the energy higher than the band-gap energy, which absorbs the light and makes the quantum dot
In excitation state, then the quantum dot emission has the light of specific wavelength and returns to ground state, and from the light of the quantum dot emission
There can be the wavelength corresponding to the band-gap energy.Thus, by controlling the size of quantum dot and forming the hair of optional quantum dot
Light characteristic, therefore quantum dot is widely used in various light emitting devices.
The method of control quantum dot size is mainly to adjust the ratio of reactant or by adjusting the reaction time at present.So
And when controlling quantum dot size by adjusting the ratio of reactant, the ratio of certain reactants is too low to will cause target product
Yield it is very few and the phenomenon that lead to luminescent decay, so there is adjustment bottleneck.And quantum dot is controlled by adjusting the reaction time
When size, if once injecting reactant, moment reaches supersaturation and is precipitated quantum dot in a solvent, as Ostwald is cured
The extension of time, partial size become larger；If persistently inject reactant, with the increase of reaction volume, partial size is gradually increased.
Thus either once still persistently injection reactant prepares quantum dot to injection reactant, is all based on an initial size then
The size is gradually increased, and can not prepare the quantum dot also small compared with initial size.
Therefore, the prior art could be improved.
