Lattice defects in the rarticle of silver island films have been observed byelectron microscore. Transmittance sr>ectra of these films were measured in theregion of r>lasma resonance absorr>tion and comr>ared with sr>ectra calculated sythe classical model of the SIZC effect. The agreement between experimental anacalculated half-widths was found for rarticles from 18 to 22 A in d iameter, butfor the r>articles larger than 26 A the exr:>erimental half-width was found to bebroader than the calculated one. This discrepancy is attributed to the increasedelectron-lattice defects scattering. Electron-lattice defect relaxatnon frequenciescalculated from experimental half-widths increase with the particle size. Thissize dependence is interpreted by the particle growth due to the agglomeration.The exclusion of lattice defects by annealing was difficult.
