This applet calculates the modifications of the radiative decay rate, the total decay rate, and the quantum efficiency of an optical emitter in close proximity to a prolate-shaped metal nanoparticle. The applet can be used to get a flavor on how the luminescence properties of the emitter depend on the large number of parameters that are involved.

For information on the parameters, click the question mark.

For more information on the calculation methods and for an analysis of how metal nanoparticles should be designed to optimize decay rate modifications, see our recent paper (Mertens et al, Phys. Rev. B 76, 115123 (2007)) and our new manuscript.
