| Abstract: | In order to avoid the influence of the heat treatment on the properties of organic-metal nanoscale-doped composite materials prepared by conventional wet chemical process, a new process for material synthesis is presented. The ternary system composite doped with organic-metal dopant has been successfully synthesized at room temperature. The thought about fully coating of dyes on the surface of metallic nanoparticles is realized. The microstructure of the sample is observed by TEM, and the UV-Vis absorption spectra of the sample are measured as well. The structural model for describing the materials is given and the mechanism of experimental results is analyzed by the model successfully. |
