Method for the preparation of IV-VI semiconductor nanoparticles

申请人：Cho Kyung-Sang

公开号：US20060110313A1

公开（公告）日：2006-05-25

A high temperature (on the order of about 90° C. or above) non-aqueous synthetic procedure for the preparation of substantially monodisperse IV-VI semiconductor nanoparticles (quantum dots) is provided. The procedure includes first introducing a first precursor selected from the group consisting of a molecular precursor of a Group IV element and a molecular precursor of a Group VI element into a reaction vessel that comprises at least an organic solvent to form a mixture. Next, the mixture is heated to a temperature of about 90° C. or above and thereafter a second precursor which is different from the first precursor and is selected from the group consisting of a molecular precursor of a Group IV element and a molecular precursor of a Group VI element is added into the heated mixture. The reaction mixture is then mixed to initiate nucleation of IV-VI nanocrystals and the temperature of the reaction mixture is controlled to provide substantially monodispersed IV-VI nanoparticles having a diameter of about 20 nm or less.

提供了一种高温（大约90°C或以上）的非水合成方法，用于制备基本单分散的IV-VI半导体纳米颗粒（量子点）。该方法首先将选自Group IV元素的分子前体或Group VI元素的分子前体之一的第一前体引入至至少包含有机溶剂的反应容器中形成混合物。接下来，将混合物加热至大约90°C或以上，然后向加热的混合物中加入与第一前体不同的第二前体，所述第二前体选自Group IV元素的分子前体或Group VI元素的分子前体之一。然后混合反应物以启动IV-VI纳米晶的成核，并控制反应物的温度，以提供直径约为20nm或更小的基本单分散的IV-VI纳米颗粒。
