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

Introducing the newly designed 'meta-grid' of nanoparticles into the epoxy casing of light-emitting diodes (LEDs) offers a substantial improvement of their light output, besides increasing lifetime, according to the scientists who invented it. A 'meta-grid' is a specially designed, optimized two-dimensional array of metallic nanoparticles, which needs to be placed at a specific location within the epoxy casing of the LEDs.
