Composition of MNCs was controlled by varying the film deposition rate, ion specie (60 keV Cu- or Ag- ions), ion flux and fluence. Linear optical absorption measurements showed formation of metal nanoparticles. Non-linear optical absorption of MNCs measured by the Z-scan method utilizing femtosecond laser pulses consisted of negative contributions from (a) metal nanoparticles and, possibly, (b) a polymer matrix. © 2005 Old City Publishing, Inc. 关键词: Composite materials;Nanostructured materials;Nonlinear optics;Chemical vapor deposition;Polymers;Thin films;Silica;Substrates;Ion implantation;Laser pulses;Metal nanoparticles;Ion mixing;Nonlinear optical response
