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 TECHNICAL ARTICLEÂ
