Scattering induced optical limiting in Si/SiO2 nanostructure dispersions
Abstract
We present evidence for scattering induced optical limiting in a suspension of Si/SiO2 nanostructures in an isopropanol solution. The structures were studied by open and closed aperture z-scan with 6ns Gaussian pulses at 532nm from a frequency doubled, Q switched Nd:YAG laser. The linear absorption of the nanostructures displayed evidence of quantum confinement. An intensity dependent scattering study illustrated the contribution to optical …
