摘　　要：In this work,different types of Mn-doped ZnS QDs were prepared and applied to study of the chemiluminescence reaction of hydrogen peroxide and periodate. The effects of the size of nanoparticles,shell protection and the stabilizing agents on chemilu-minescence intensity were studied. The results indicated that the size of quantum dots was not the only factor to enhance the intensity of chemiluminescence system. Different stabilizing agents and the silica film protection will also influence the performance of the quantum dots in the chemiluminescence reaction. A CL spectrum was examined by using a series of high-energy cut-off optical filters and a possible mechanism of the CL was also proposed.In this work, different types of Mn-doped ZnS QDs were prepared and applied to study of the chemiluminescence reaction of hydrogen peroxide and periodate.
