【 摘 要 】

Several noble metal nanoparticles doped sol–gel derived thin coloured films have been synthesized and characterized. These are pure (Ag, Au, Cu and Pt), mixed/alloy (Ag–Cu, Au–Cu, Au–Ag and Au–Pt) nanoparticles in SiO2, Au in mixed SiO2–TiO2 and SiO2–ZrO2, Au and Ag nanoparticles in inorganic–organic hybrid film matrices etc. This investigation leads to the development of tailor-made coloured coatings by tuning the surface plasmon resonance (SPR) band positions originating from the embedded nanometals by controlling mainly
