摘　　要：超声波辐射下,以硝酸铅、硫代乙酰胺为原料制备了PbS纳米晶,用TEM和XRD研究了聚乙二醇用量和反应时间对PbS纳米晶的影响。结果表明,超声波能抑制颗粒团聚;聚乙二醇具有良好的分散性和一维导向性。PbS纳米晶粒径较细、纳米棒长度为2μm。PbS nanocrystals was prepared under ultrasonic irradiation from Pb （NO3 ）2 and thioacetamide. The effects of the amount of polyethylene glycol（PEG） and reaction time on PbS nanocrystals were studied by TEM and XRD. The results showed that the ultrasonic wave can inhibit the agglomeration of particles. PEG exhibits good dispersity and one dimension guidance quality. The PbS is rodlike with length of 2μm.
