Abstract. The method of pulsed laser deposition in vacuum from forward and backward
particle flows from an erosion torch was used to prepare silver films and Ag/Al 2 O 3
nanocomposite films. Measured were transmission and time-resolved photoluminescence
spectra. The authors studied the influence of conditions for film formation on their
optical and photoluminescent properties. For the first time, there observed was
luminescence with quantum energy 1.6 eV and relaxation times up to several
microseconds.
Keywords: nanocomposite film, metal in oxide matrix, time-resolved photolumines-
cence, local surface plasmon resonance, pulsed laser deposition.
