Two-photon-excited fluorescence (TPEF) enhancement effect in CdSe quantum dot modified Au nanoparticle was theoretically investigated. TPEF enhancement factor was obtained in dipole approximation by taking surface plasmon resonance enhancement effect and nonradiative energy transfer to Au NP into account. An available method to achieve sufficient TPEF enhancement factor with noble metal nanoparticles was concluded from the analysis of numerical simulation. Greater TPEF enhancement effect will be obtained by adjusting the surface plasmon resonant peak of noble metal nanoparticles to the excitation wavelength. This theoretical analysis result was proved to be appropriate to the reported experimental results.
