Abstract
In-depth imaging in biology requires the development of bright nonlinear labels (with either fluorescence or frequency conversion properties) which excitation can be done within the transparency window of biological tissues. In this presentation, I will show that, although bulk gold is known to present very low luminescence quantum yield, gold nanorods present a huge 2-photon luminescence with an apparent high influence of the particle volume. After clarifying the role of plasmon in these properties, I will also discuss the interest of taking profit of plasmons to enhance the frequency conversion properties of dielectric nanocrystals.
