Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than with previous designs — a speed record, and a step toward realizing superfast light-emitting diodes (LEDs) for nanophotonic devices, such as telecommunication lasers and as single-photon sources for quantum cryptography.
