EFFICIENT AND DIRECTED NANO-LIGHT EMITTING DIODE, AND METHOD FOR MAKING SAME

This technology relates to an ultra high efficient LED system with the capability to modify an LEDs radiation pattern by changing its physical dimension-emission beam shape. The ultra high efficiency and redistribution of light has been achieved without the use of a back reflector. The ultra high efficiency can be controlled by changing the size of the nanorods within the design. These features can be very useful for bio-sensing and bio-imaging applications.
