The American Chemical Society is claiming that the "holy grail" of the LED world has been reached. A pair of Indian Scientists have created a pure white LED. No longer will we have to suffer with odd blue- or yellow-like white LED's. The method used to achieve the white color was so blatantly obvious, they used "phosphors made from semiconductor nanocrystals of cadmium sulfide mixed with manganese." The scientific duo is currently attempting to raise its production consistency so that it can be brought to the masses. [Physorg via ACS]
