Abstract
Nanoscale Ag particles uniformly embedded in BaTiO3 thin films were pr epared by radio-frequency cosputtering technique. The measurement of o ptical absorption was made on as-deposited and annealed samples. The e xperimental results indicated that no absorption peak was observed in as-deposited sample, but the absorption peak appeared after the sample was annealed at high temperature. The interaction between external mo lecules and the surface of small Ag particles seems to have strong inf luence on the absorption peak of small Ag particles. (C) 1998 Elsevier Science B.V.
