Shinier, robust and pinchpenny LEDs
India Science Wire
New Delhi, Aug 07 (India Science Wire): Light-emitting diodes (LEDs) have replaced the ordinary
bulbs and they can further reduce the energy needs on large scale. Researchers from the Indian
Institute of Technology (IIT), Guwahati and Imperial College London, UK, have developed a tailored
‘meta-grid’ of nanoparticles that could make light-emitting diodes (LEDs) even brighter, energy-
efficient and durable. 'Meta-grid' or ‘metamaterial grid’ is a specifically patterned array (grid) of
nanoparticles acting as metamaterials, capable of exhibiting extraordinary optical properties.
Over the years, a significant research drive towards this objective is in exploring new materials for
LED-chip encapsulation, mostly by deploying either higher refractive in...
