Improving performance of LEDs is a continuous task for researchers. A team consisting of researchers of Imperial College London introduced a method of embedding tailored meta-grid of nanoparticles to LEDs to enhance their light output and lifetime. (Image: Debabrata Sikdar, John B. Pendry, and Alexei A. Kornyshev) The method was published in Light Science & Application in July by Dr. Debabrata Sikdar, Prof. Sir John B. Pendry and Prof. Alexei Kornyshev from Imperial College London. They reported an alternative route for improving light extrac...
