摘要： A doping method for forming quantum dots is disclosed, which includes following steps: providing a first precursor solution for a group II element and a second precursor solution for a group VI element; heating and mixing the first precursor solution and the second precursor solution for forming a plurality of II–VI compound cores of the quantum dots dispersing in a melting mixed solution; and injecting a third precursor solution for a group VI element and a forth precursor solution with at least one dopant to the mixed solution in turn at a fixed time interval in order to form quantum dots with multi-shell dopant; wherein the dopant described here is selected from a group consisting of transitional metal and halogen elements. This method of the invention can dope the dopants in the inner quantum dot and enhance the emission intensity efficiently.

摘要： An apparatus for manufacturing a quantum-dot element is disclosed. The apparatus includes a reaction chamber for evaporating or sputtering at least one electrode layer or at least one buffer layer on the substrate. The substrate-supporting base is located inside the reaction chamber for fixing the substrate. The atomizer has a gas inlet and a sample inlet. More specifically, the gas inlet and the sample inlet feed the atomizer respectively with a gas and a precursor solution having a plurality of functionalized quantum dots, and thereby form a quantum-dot layer on the substrate. The apparatus of the present invention can form a quantum dot layer with uniformly distributed quantum dots and integrate the processes for forming a quantum-dot layer, a buffer layer, and an electrode layer together at the same chamber. Therefore, the quality of produced element can be substantially improved.
