NanoLEDs: bringing nanophotonics into solid-state lighting

Current blue LEDs coated with phosphor materials are operated at daunting power densities and temperatures to generate very high white light illumination levels for general lighting, automotive, projection and displays. These operation conditions require tight control over efficiency budgets and material performance at all stages, i.e., light generation at very high current densities, photon circulation in the LED chip die, coupling of light for the excitation of the phosphor, and conversion into white light of desired spectral and angular quality in the phosphor material. In this project, researchers quantitatively study the implementation of nanostructured surfaces designed to interact optimally with the emission of LEDs to boost blue light emission and white light conversion efficiencies
