Abstract: Gold nano composites with ORMOCER matrices have been prepared by a controlled precipitation process from HAuCl4 solutions, using silanes of the type NH2[(CH2)2NH]x(CH2)3Si(OR)3 (with x=1,2) as a stabilizing agents. In the first step, formation and properties of the ligand stabilized colloidal suspensions was investigated. The different ligands are influencing the adsorption spectra, showing surface plasmon bands between 380 and 700 nm. With the diamo silane, photoreduction is required for the colloid formation, whereas in the case of triamo silane, the colloid formation occurs spontaneously. In the second step, the formation of colloid films on glass substrates was investigated.
