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.<br><br>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.<br><br><a href="http://www.princeton.edu/engineering/news/archive/?id=13571">READ MORE ON PRINCETON | SCHOOL OF ENGINEERING AND APPLIED SCIENCES</a><br><br>
