Improving efficiency, brightness of perovskite LEDs

Advances in organic phosphorescent materials are opening new opportunities for organic light-emitting diodes for combined electronics and light applications, including solar cells, photodiodes, optical fibers and lasers. While low-dimensional luminescent materials, like the calcium titanium oxide mineral perovskite, have promising optical properties, their performance remains insufficient compared to conventional organic LEDs. A recent study explores a new approach using an exciton confinement effect to optimize highly efficient perovskite LEDs.
