Soon you may be saying Thomas who? This is really some invention from Michael Bowers, a graduate student at Vanderbilt University. And it seems to have been done by accident.
When you shine a light on quantum dots or apply electricity to them, they react by producing their own light, normally a bright, vibrant color. But when Bowers shined a laser on his batch of dots, something unexpected happened.
"I was surprised when a white glow covered the table," Bowers said. "The quantum dots were supposed to emit blue light, but instead they were giving off a beautiful white glow."
Then Bowers and another student got the idea to stir the dots into polyurethane and coat a blue LED light bulb with the mix. The lumpy bulb wasn't pretty, but it produced white light similar to a regular light bulb.
Now that is pretty cool science. Kind of like the legend that an apple falling from a tree made Isaac Newton create his theoreys of motion. This LED invention has the potential to change the world and make the US alot more energy independent. Good job Vanderbilt University grad student Michael Bowers.
