摘要：
Photoluminescence characteristics of hybrid quantum dots CdSe/CdS deposited on the surface of silica containing the layer of ion-synthesized silver nanoparticles were studied. The quenching or enhancement of the luminescence depending on distance between silver nanoparticles and quantum dots layers was detected. The optimal spacer layer and excitation waveleghth for the highest intensity of their photoluminescence in the plasmon field of metal nanoparticles was defined.
