Light scattering particles made of TiO, BaSO, SiO, or AlOhave been used in a QD layer of a QD-LED for enhancing luminous intensity. However, the light scatters are found to decline the light conversion efficiency of the QD layer. In view of that, the present invention particularly discloses a light conversion material with high conversion efficiency for use in the QD-LED. The light conversion material mainly comprises a polymer matrix, a plurality of 3D photonic crystals dispersed in the polymer matrix, and a plurality of quantum dots dispersed in the polymer matrix, wherein each of the plurality of 3D photonic crystals is formed by applying a self-assembly process to a plurality of polymer beads. Moreover, a variety of experimental data have proved that, this light conversion material indeed exhibits outstanding photoluminescence intensity and light conversion efficiency both superior than that of the conventionally-used QD layer.

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.
