Computers aid discovery of new, inexpensive material to make LEDs with high color quality
Computers have helped researchers develop a new phosphor that can make LEDs cheaper and render colors more accurately. Researchers predicted the new phosphor using supercomputers and data mining algorithms, then developed a simple recipe to make it in the lab. Unlike many phosphors, this one is made of inexpensive, earth-abundant elements and can easily be made using industrial methods. As computers predicted, the new phosphor performed well in tests and in LED prototypes.
