The invention discloses a quantum dot nuclear synthesis device, which comprises a nuclear reaction region, wherein the nuclear reaction region comprises at least one spiral reaction tubes; a path groove which is in a direction opposite to the spiral shape and enables reactants in the reaction tube to generate bubbling effects through friction is formed in the inner wall of the spiral reaction tube; a heating region covers the front section of the nuclear reaction region; a cooling region covers the back section of the reaction region; a plurality of injection openings are formed in the front end of the nuclear reaction region; a plurality of seston discharging openings are formed in the back end of the nuclear reaction region; the front end of the nuclear reaction region is connected with a pressurization device. The invention also discloses the quantum dot nuclear synthesis device. The quantum dot nuclear synthesis device has the advantages that the structure is simple and reliable; through the path groove formed in the spiral reaction tube, the reactants can be stirred; the passing time of the reactants in the spiral reaction tube can be controlled through regulating the inner diameter and the length of the spiral reaction tube by aiming at different kinds of nucleuses to be synthesized, so that the high-quality nucleuses can be obtained.

Description

technical field [0001] The invention relates to the field of quantum dot synthesis, in particular to a quantum dot nuclear synthesis device and a quantum dot nuclear synthesis method implemented by the quantum dot nuclear synthesis device. Background technique [0002] In the prior art, the synthesis method of quantum dots is a solution process, which mainly consists of a flask surrounded by a heating jacket, a magnetic stirrer that can make the solution inside the flask uniform, and a temperature regulator and a thermometer to control the temperature of the solution. In addition, a capacitor to maintain a stable concentration and a manifold that can switch vacuum / nitrogen atmosphere are added. [0003] The synthesis method is to use the precursor (precursor) organic compound to synthesize the core (core). In order to make the synthesized core and stabilizer form a proper shell in the mixing and stirring reactor, the precursor is repeatedly injected to form a structurally st...

AI Technical Summary

Problems solved by technology

Forced stirring by magnetic bar or stirrer in each reaction process, although this is a well-known method to achieve relatively uniform stirring, but according to the amount of reactants, the reaction stirring speed will be different, which will affect the size of the particles and stabilize the nanoparticles Formation

[0006] This existing synthesis method also requires precursor reactors, nuclear reactors, core / shell reactors, etc., because it is re-measured and measured after each reaction, and then synthesized, so there is a disadvantage that continuous operation cannot be performed.

Moreover, due to differences in reaction time, particle separation, etc., it may not be possible to obtain nanoparticles with uniform characteristics.
