Scientists from the University of rochester have uncovered the basic physics thind the phenomenon of an optical quirk called “blinking” and along with Kodak researchers they created a nanocrystal that constantly emits light.
With blink-free nanocrystals, Krauss (an expert in nanocrystals) believes lasers and lighting could be incredibly cheap and easy to fabricate.
Now, different color laser light is created using different materials and processes, but with the new nanocrystals a single fabrication process can create any color laser. To alter the light color, an engineer needs only to alter the size of the nanocrystal, which Krauss says is a relatively simple task.
The same is true of what could one day be OLED’s successor. Essentially, “painting” a grid of differently sized nanocrystals onto a flat surface could create computer displays as thin as paper, or a wall that lights a room in any desired color.
