摘要：

We evaluate multi walled carbon nanotubes decorated with gold or silver nanoparticles suspended in water regarding their nonlinear attenuation characteristics for nanosecond laser pulses. The results are compared to pure multi walled carbon nanotubes. A Q-switched Nd:YAG laser working at a wavelength of 1064 or 532 nm, with a pulse width of 3 ns is used to characterize their optical limiting behaviour by fluence dependent transmittance measurements. Our experiments show that the properties of the hybrid materials, measured at both wavelengths, could be improved compared to plain multi walled carbon nanotubes.
