First Pure White LED
September 26, 2007 by Lauren
 We're all fans of LED, and it's about to get better than ever. Ever notice that nasty tint associated with LED? It's usually blue or yellow-ish, and a major turn-off either way, but no more. Unlike the existing and unstable versions, this LED is truly pure white. According to Physorg.com:
"The researchers report the
first success in developing a new LED based on a new phosphor from
semiconductor nanocrystals of cadmium sulfide mixed with manganese."
Well, duh! We didn't we think of that? Scientists have had difficulty with developing pure white light, as the evidence of tinted lighting shows, but it seems that they've finally tinkered around enough to figure it all out. Not a moment too soon, either; this scientific discovery leads us to a stable version of white light that looks precisely the way it is supposed to look, even as time draws on.
Of course, now that we've successfully rendered it, the time has come to tamper with it even more. The light still has to be tweaked to increase efficiency so that we can actually use this stuff in our own daily lives. The resulting, practical versions of white LEDs would be brighter and would last longer than the other typical light sources we rely on (i.e. incandescent/fluorescent lighting). From there, we could even start replacing such lamps with the new and improved light.
