Perovskite Nanoplatelets Yield Bright LEDs

Perovskites have become the hottest material for solar cells because they are cheap and very easy to process. They’ve also been tapped for use in light-emitting diodes and lasers, but LEDs incorporating materials with the perovskite crystal structure have not been very bright. But researchers at Florida State University (FSU) now report that they have made perovskite LEDs that are more than four times as bright as earlier versions. They have a brightness of over 10,000 candelas per square meter, comparable to that of organic LEDs and quantum dot LEDs.
