Princeton University researchers have developed a new method
to increase the brightness, efficiency and clarity of LEDs, which are widely
used on smartphones and portable electronics as well as becoming increasingly
common in lighting.
Using a new nanoscale structure, the researchers, led by
electrical engineering professor Stephen Chou, increased the brightness and
efficiency of LEDs made of organic materials (flexible carbon-based sheets) by
57 percent. The researchers also report their method should yield similar
improvements in LEDs made in inorganic (silicon-based) materials used most
commonly today.
