摘要：

Optical limiting frequency and bandwidth of
nanocomposite films containing gold nanorods embedded
in a dielectric matrix were investigated by using Maxwell–
Garnett (MG) effective medium model and quasi-static theory.
Because of the morphological anisotropy of the gold
nanorods, there are two bands of optical limiting taking
place in the visible and near infrared region. A large variation
of the optical limiting frequency from 530 to 820 nm
was obtained by increasing the aspect ratio of gold nanorods
from 1.0 to 5.0. Furthermore, the bandwidth of optical limiting
can also been tuned from 50 to 190 nm by increasing
the gold volume fraction from 10% to 30%.
