Nanocomposite thin films formed by nanometer-sized metal particles embedded in BaTiO3 matrices (Au/BaTiO3,Fe/BaTiO3) were fabricated using pulsed laser deposition technique.The morphology and chemical state of the embedded metal particles were analyzed by transmission electron microscopy and x-ray photoelectron spectroscopy,respectively.The absorption peak due to the surface plasmon resonance of Au particles was observed at the wavelength of about 580nm in Au/BaTiO3 films.However,optical absorption spectra in the wavelength range of 330—800nm showed no significant resonance peak in Fe/BaTiO3 films.The results were explained by Mie theory.
