Enhanced nonlinear transmittance by complementary nonlinear mechanisms: A reverse-saturable absorbing dye blended with nonlinear-scattering carbon nanotubes Article uri icon

abstract

  • The preparation of a nonlinear scattering system blended with a reverse saturable absorbing (RSA) dye for complimentary nonlinear transmission was discussed. Nitrogen-doped multiwalled carbon nanotubes were functionalized for compatibilization in alcohols and blended with a carbocyanine dye. The nonlinear optical response of the composite system was investigated. It was found that the mechanism for nonlinear scattering is due to the creation of new scattering centers by carbon sublimation and ionized carbon microplasmas.
