FEASIBILITY OF EFFICIENT BLUE LIGHT EMITTING DIODES

THERE IS A NEED FOR HIGHER EFFICIENCY BLUE LEDS FOR USES SUCH AS DISCRETE LAMPS AND ESPECIALLY MULTI-COLOR LED DISPLAYS. WHEN COMPARED TO GREEN AND RED LEDS, WHICH HAVE EFFICIENCIES AS HIGH AS 10%, BLUE LEDS ARE PRESENTLY LESS THAN 0.1% EFFICIENT. THEREFORE, IT IS NECESSARY TO INCREASE THEIR EFFICIENCY TO MAKE THEM COMPATIBLE WITH THE DRIVE ELECTRONICS PRESENTLY USED FOR RED AND GREEN LEDS. IN PHASE I, WE WILL ADDRESS THE FEASIBILITY OF IMPROVING THE RADIANT EFFICIENCY OF BLUE LED MATERIAL. IN PHASE II, WE WILL DEVELOP PROOF OF CONCEPT BLUE LEDS FOR USE IN MULTI-COLOR DISPLAYS. COMMERCIALIZATION WILL BE CARRIED OUT IN PHASE III. ANTICIPATED BENEFITS/POTENTIAL APPLICATIONS - THIS WORK WILL RESULT IN BLUE LED MATERIAL FOR BRIGHTER, MORE EFFICIENT DISCRETE LED LAMPS AND MULTI-COLOR LED DISPLAYS. THE INCREASED LUMINESCENCE EFFICIENCY WILL ALSO BE DIRECTLY APPLICABLE TO BLUE LASERS MADE FROM THE SAME MATERIAL.
