摘　　要：在Zhang制备PbS量子点技术的基础上,作者对其技术进行了改进,通过引入溶剂和反应添加剂,在室温、常压下合成了PbS量子点。由于该改进技术可通过选择不同种类的溶剂、不同种类的添加剂、不同的反应物浓度以及不同的反应时间,来控制PbS量子点的尺寸及表面形貌,这为化学溶液法室温制备PbS量子点带来了极强的可控性。这种廉价实用的室温、常压量子点制备技术在量子点红外探测器、生物标签、有机/无机复合材料等材料与器件等领域有潜在的应用价值。Based on Zhang＇s PbS Quantum Dots （QDs） method, the authors of this paper improved Zhang＇s method by introducing solvent and reaction additives to the reaction system. PbS QDs have been prepared at room temperature, atmospheric pressure. The sizes and morphologies of PbS QDs may be easily controlled by using solvents, additives, concentrations of reactants as well as reaction time, which resulted in the strong controllability for the preparation of PbS QDs from Chemical Solution Method （CSM） at room temperature. This low-cost, room temperature, atmospheric pressure QDs preparation technique has potential applications in the fields of QDs infrared detector, biological label, organic/inorganic complex materials.
