The development of a long-range and efficient Förster resonance energy transfer (FRET) process is essential for its application in key enabling optoelectronic sensing technologies. Via controlling the delocalization donor's electric field Purcell enhancements, we experimentally demonstrate high-efficiency using plasmonic nanogap formed between silver nanoparticle an extended film. Our measurements show that FRET range can be to over 200 nm while keeping efficiency 0.38, achieving enhancement...
Förster resonance energy transfer (FRET) is a fundamental phenomenon in photosynthesis and of increasing importance for the development enhancement wide range optoelectronic devices, including color-tuning LEDs lasers, light harvesting, sensing systems, quantum computing. Despite its importance, questions remain unanswered on FRET rate dependency local density optical states (LDOS). In this work, we investigate directly, both theoretically experimentally, using 30 nm plasmonic nanogaps...
We report evidence of possible migration metal nanoparticles in nanoparticle-polymer memristor devices. In bi-layer devices, having a bottom layer containing mixed nanoparticle polymer blend and top just the polymer, light emission from fluorescent dye was observed to change during application an electric potential. Control fluorescence by changing magnitude direction applied voltage support mechanism field induced into layer. Potential applications as switches displays optoelectronics are...
Abstract Successful control of Förster resonance energy transfer (FRET) through the engineering local density optical states (LDOS) will allow us to develop novel strategies fully exploit this phenomenon in key enabling technologies. Here we present an experimental and theoretical study on effect LDOS FRET rate efficiency plasmonic nanopatch antennas formed between a gold nanoparticle extended silver film. Our results reveal that similar levels exhibit comparable efficiency, demonstrating...
