Metal nanoparticle doped coloured coatings on glasses and plastics through tuning of surface plasmon band position

[摘要] Several noble metal nanoparticles doped solâ€�?�gel derived thin coloured films have been synthesized and characterized. These are pure (Ag, Au, Cu and Pt), mixed/alloy (Agâ€�?�Cu, Auâ€�?�Cu, Auâ€�?�Ag and Auâ€�?�Pt) nanoparticles in SiO₂, Au in mixed SiO₂â€�?�TiO₂ and SiO₂â€�?�ZrO₂, Au and Ag nanoparticles in inorganicâ€�?�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
