Evolution of surface plasmon resonance for silver particle film on mesoporous Si02 and soda-lime glass during heating in air and H2.
Thin and thick Ag films on SiO2 substrates (mesoporous SiO2 and Soda-lime glass) were respectively prepared by thermal evaporation and spin-coating. The evolution of surface plasmon resonance absorption of the as-prepared samples was investigated when alternately heated in air and H2. It has been shown that the evolution behaviours were very different with Ag film thickness and substrates. The results were explained in terms of subtle difference of the two SiO2-based substrates in micro-structure or chemical composition, the redox of silver and relative Ag content.
