True White LED Light Discovered
A white LED light accidentally discovered by a Vanderbilt University graduate student, Michael Bowers last week, may change the way we light up our lives.
This breakthrough couldn’t have come at a better time, the LED light consumes less energy and lasts about 50 times longer then a conventional light, but it also produces twice the power of that of a 60-watt bulb.
Bowers was attempting to create very small quantum dots or crystals just a few nanometers large, that’s less than 1/1000th the width of a human hair. When he shined a laser on his group of dots, the unexpected happened, a soft beautiful white glow covered the table.
