A quantum dot structure includes a core and an inner shell. The core is a single crystal of a compound M1C1, and has a core surface having a first region and a second region. The first region has a crystal plane that is inactive with oxygen, and the second region has a crystal plane that is easily reactive with oxygen. The inner shell is a single crystal of a compound M2C2, and is formed on the first region of the core surface. A method for making the quantum dot structure is also disclosed.

Quantum dot structure with excellent stability and method for making the same

A quantum dot is represented by ZnCdSSeand has a size ranging from 7 nm to 20 nm, wherein 0&#x3c;x&#x3c;0.2, 0.005&#x2264;y&#x3c;0.2, and Zn, Cd, S, and Se are non-uniformly distributed therein.

The present invention mainly provides a non-contact reactor consisting of a reaction vessel having a particularly-designed size, a plurality of injection modules, an agitator, a heat exchange module, and an electrical gate valve module. Operators can inject at least one precursor solution into the reaction nanometer-scale semiconductor crystallites vessel and make the injected precursor solution reach a specific position in the reaction vessel by using the electrical gate valve to control the injection pressure of the injection modules. Moreover, the operators can further control the rotation speed of the agitator through a controller, so as to evenly and quickly mix the injected precursor solution and a specific solution pre-filled into the reaction vessel to a mixture solution; therefore, the acceleration of production rate and the enhance of production yield of the semiconductor nanocrystals are carried out.
