Plasmon-exciton coupling in nanostructured metal-semiconductor composite films
Nonlinear optical response of metal-semiconductor Zn0.8Co0.2O/Au nanocomposite films was studied experimentally and theoretically. Z-scan measurements revealed a positive nonlinear index of refraction of the composite film. Fluorescent spectroscopy measurements exhibited a narrow sharp peak that mig...

| description | Nonlinear optical response of metal-semiconductor Zn0.8Co0.2O/Au nanocomposite films was studied experimentally and theoretically. Z-scan measurements revealed a positive nonlinear index of refraction of the composite film. Fluorescent spectroscopy measurements exhibited a narrow sharp peak that might be attributed to exciton peak of semiconductor nanostructured thin film enhanced by nearby gold nanoparticles. Classical electrodynamic calculations of a quantum dot in close proximity to a gold nanoparticle agree well with the experimentally observed normalized quantum efficiency. |
