Abstract

A series of metal-cluster-organically modified silicate, or Ormosil, nanocomposites were prepared by the sol-gel method. Each of the metals (Ag, Au, Cu, and Pt), was incorporated individually into the Ormosil matrices at various weight percents by reduction of the appropriate metal salt. The preparation for these metal-cluster doped-Ormosils is described. Ormosil proved to be an ideal matrix material, offering excellent transparency and good cracking resistance. The presence of the metal clusters inside the Ormosil matrices was detected by transmission electron microscope and verified by X-ray diffraction. Optical absorption. measurements of these nanocomposites are also presented.
