    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.
