The enhanced Forster resonance energy transfer is obtained in recent experiments. One of most important experimental fact is the observed strong enhance of donor fluorescence with increasing the concentration of metallic nano-particle acceptors in the first stage. We propose three types of energy transfer mechanisms (Forster FRET, surface SET and Coulomb CET) and predict simple relations for their dependences on the concentration of metallic nano-particles. The competition of these mechanisms leads to the transfer intensity dependence on the concentration dependence of metallic nano-particles. Using these assumptions, we obtain quite good agreement of the theoretical results with experimental data.
