Structure of a Large Perovskite LED

Caption

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, in this week's Applied Physics Reviews, explores a new approach using an exciton confinement effect to optimize highly efficient perovskite LEDs. This image shows the structure of a large perovskite LED, where a layer of zinc oxide was deposited on the a-zinc silicate electron transport layer, providing greater brightness with better power efficiency.
