Nanotechnology results in better and cheaper LEDS for phones and lighting

September 25, 2014

Princeton University researchers, led by Prof. Stephen Chou, have developed a new method to increase the brightness, efficiency and clarity of LEDs. 
Using a new nanoscale structure, the researchers 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.  Complete article can be found here
