WASHINGTON:
Scientists have developed a new type of light-emitting diode (LED)
using an organic-inorganic hybrid that could lead to cheaper and
brighter lights and displays in the future.
The researchers used a class of materials called organometal halide perovskites to build a highly functioning LED. Perovskites are any materials with the same type of crystal structure as calcium titanium oxide. "The material glowed at about 10,000 candelas per square metre at a driving voltage of 12V," reserchers said.
"Such brightness is due to the inherent high luminescent efficiency of this surface-treated, highly crystalline nanomaterial," said Hanwei Gao, assistant professor of physics. Present LEDs glow at about 400 candelas per square meter.
