By employing the finite difference time domain method, we study the fluorescence enhancement of molecules coupled to an asymmetric plasmonic nanoshell. This kind of nanoparticles can considerably enhance flourescence rate. For this purpose, we consider a nanoshell consisting of a silica core and a golden shell. It is shown that, with proper selection of core dimension, core material, core displacement, molecular distance and direction the fluorescence rate can be considerably increased.
