Tailored meta-grid of nanoparticles boosting performance of light-emitting diodes

Phys.org  July 29, 2020 Current methods to use new materials for increasing LED light output are has led to the LED chips becoming bulkier or costly to manufacture. According to a theoretical model proposed by researchers in the UK a significant enhancement in light extraction from LEDs can be achieved by boosting the transmission across LED-chip/encapsulant interface. They propose introducing a monolayer of plasmonic nanoparticles on top of the LED chip which can reduce the Fresnel reflection loss at the chip/encapsulant interface. A similar effect is also applicable for enhancing the trapping of light in solar cells…read more. Open Access […]
