Abstract: Ag–Polyvinyl alcohol (Ag–PVA) films have been prepared, and the influence of annealing time upon the variation of cluster size has been analyzed using optical absorption, emission and Fourier-transform infrared (FTIR) spectra. Measurements of optical spectra show that the surface plasmon resonance lies around 420 nm, and confirm the growth of Ag clusters. Measurements of FTIR spectra were carried out to identify the role of chemical interface damping which influenced the broadening of the absorption band. The emission peak was observed at 540 nm for clusters which were annealed for 1 min as well as 2 min.
