Researchers from the University of Wisconsin–Madison have discovered that a perovskite material could greatly enhance the technology of vacuum electronics. The material is capable of promoting the output power of the electron beam, and enables remote sensing and long-distance communications for a much lower energy cost than currently spent.

The researchers received a $1.3 million grant from the Defense Advanced Research Projects Agency. They aimed to synthesize large quantities of the material and additionally analyze its properties. They also hope to locate other applications where this concept can be utilized.

Researchers from the King Abdullah University of Science and Technology (KAUST) have designed a system that uses an innovative color converter based on luminescent materials known as phosphors, which are commonly used in LED lights, and combines them with nanocrystals of perovskite. This system has achieved record bandwidth, providing a data transmission rate of 2Gbit per second.

The major achievements in this work are breaking the record for data communication using visible light and, even more impressively, producing white light with a very high color-rendering index of 89, by designing a special color converter based on hybrid perovskite nanocrystals. The work demonstrates white light as both a lighting source and a system for ultra-high-speed data communications.
