Influence of localized surface plasmons on Pauli blocking and optical limiting in graphene under femtosecond pumping

SR Bongu, PB Bisht, RCK Namboodiri… - Journal of Applied …, 2014 - pubs.aip.org
The Pauli blocking limit and optical limiting threshold have been found to be modified
following silver-nanoparticle decoration of functionalized hydrogen induced exfoliated
graphene. Femtosecond Z-scan experiments have been used to measure the Pauli blocking
range, optical limiting threshold, and the third order nonlinear susceptibility (χ (3)) values.
The observed results have been explained by modified band structure of graphene in the
presence of silver nanoparticles and their localized surface plasmon resonances.
