Research Abstract

We could achieve the quenching-free fluorescence based on nonmetallic particles. Calculations based on the Mie theory suggested high enhancement factors for GaP and Si particles. Experiments performed with GaP particles and dye molecules indeed demonstrated the fluorescence enhancement with an enhancement factor as high as 140. A high enhancement was observed even when the molecules are located within 10 nm away from the particle surfaces, demonstrating that the fluorescence is quenching free. We also theoretically examined the high electric field enhancement in planar dielectric multilayer systems. The dielectric waveguide is expected to be very much suited to the quenching free fluorescence enhancement.
