Abstract

Pd colloid containing Ormocers (organically modified ceramics) havebeen prepared from Pd amino complexes of the type Pd[NH2CH2CH2NH(CH2)3Si(OMe)3]2ac2by hydrolysis and condensation (sol-gel reaction) of the silane togetherwith Si(OEt)4 and Si(OEt)3(CH2)3OCH2CHCH2O.The amino complex formation is necessary to avoid spontaneous reduction anduncontrolled colloid formations in the liquid phase. This synthesis routeleads to Pd colloid containing powders and coatings on glass. By thermalcuring (temperatures up to 500 °C) using different atmospheric conditions (N2, Ar, H2/N2) brown to deep blackcoatings on glass with transmission values from 80 to 0 % can be obtained.The average particle size can be controlled by varying the molar ratio ofthe used Pd salt (Pd(ac)2) and the aminosilane.
