本文以溶剂热法制得了CdS纳米微球体，并且采用XRD、SEM，PL等测试手段对产物进行了表征。实验结果表明：PVP、TU、Cd2＋量及反应时间对产物的颗粒大小和荧光有显著的影响。在140℃下，以硫脲为硫源，乙二醇为溶剂制得的CdS纳米微球体具有良好的形貌，外形规则，直径大约200-300 nm。荧光光谱分析表明PVP、Cd2＋量的增大及反应时间的延长使CdS微球体的峰值发生红移，TU量的增大使峰值先红移后蓝移。通过改变反应条件，实现了对CdS纳米微球的荧光性质的调控。

CdS nanospheres were prepared by hydrothermal method.XRD,SEM and PL techniques were used to characterize the as-synthesized product.It was found that the size and fluorescence were affected strongly by the [ PVP] ,[ TU] ,[ Cd2+] as well as reac-tion time.As a result,the CdS microphreres with narrow size distribution and uniform morphology are approximately 200-300nm in diameter.The result of fluorescence spectroscopy measurements reveals that the absorption peak of CdS microspheres is red shift by the increased of[PVP],[Cd2+]as well as reaction time,while first red shift after blue shift by the increased of [TU],the fluores-cence properties of CdS nanoparticles can be controlled by changing the conditions of reaction .
