-
So far, they have only managed to prevent one type of quenching called exciton-metal quenching, which was done by moving the light-emitting area further away from the electrodes.

Similarly, the largest quenching effect in OLEDs, called exciton-charge quenching, reduces the number of excitons, and occurs due to a spatial overlap of excitons and charges.

Previously, the effects of dielectric confinement have been investigated theoretically for the role they play in defining the optical properties of nanostructures, such as exciton binding energies, while the impact on electrical characteristics has largely been neglected partly due to the misconception that the relevant length scale still falls into the

In the material, the procedure produced quasiparticles called exciton polaritons, which form when photons of light and electrons collide.

That was a brilliant report delivered by E.F. Gross about the discovery of the exciton.

But the biggest drawback to using OLEDs for light display applications is that they intrinsically suffer from photon loss and exciton quenching.

bilby commented on the word exciton
"Much of today's research in electronics is geared towards obtaining faster computing and higher communication speeds. Researchers at UC San Diego are no exception, and have recently announced they have made another important step towards achieving exciton-based computation at room temperatures. Excitonics exploits the unique properties of excitons instead of the usual electrons, and promises much faster performance by interfacing more naturally with optical communications such as fiber optics."
