Technology Description:

The University of Illinois at Urbana-Champaign (UIUC) will pursue novel cubic gallium nitride-based green LEDs that, when combined with blue and red LEDs, will enable more efficient white light SSL without the use of down-converting phosphors. This project will close the “green gap” in the visible spectrum through an innovative green LED technology and create new opportunities in mainstream SSL (e.g., general lighting) and advanced SSL (e.g., connected smart lighting, visible light communication, horticulture, and medicine).

Potential Impact:

UIUC’s proposed technology could double the efficiency and halve the droop in green LEDs.

Security:

The new technology will reduce the InGaN alloy’s requirement for indium, one of the rarest metals on earth, by ~10%.

Environment:

Direct-emitting novel green light emitting diodes can enable accelerated SSL adoption, resulting in energy and environmental savings.

Economy:

UIUC’s design could reduce manufacturing costs and facilitate widespread adoption of highly efficient color-mixed SSL illumination by commercial and residential markets.
