主　　题：surface plasmon resonances two-photon fluorescence finite-difference time-domain 

摘      要：Single gold nanoshell with mutilpolar plasmon resonances is proposed to enhance two-photon fluorescence *** single emitter single nanoshell configuration is studied systematically by employing the finite-difference time-domain *** emitter located inside or outside the nanoshell at various positions leads to a significantly different enhancement *** fluorescent emitter placed outside the nanoshell can achieve large fluorescence intensity given that both the position and orientation of the emission dipole are optimally *** contrast,for the case of the emitter placed inside the nanoshell,it can experience substantial two-photon fluorescence enhancement without strict requirements upon the position and dipole *** nanoshell encapsulating many fluorescent emitters should be a promising nanocomposite configuration for bright two-photon fluorescence *** results provide a comprehensive understanding about the plasmonic-enhanced two-photon fluorescence behaviors,and the nanocomposite configuration has great potential for optical detecting,imaging and sensing in biological applications.
