Two Dimensional Materials Come to LEDs and LiFi
October 8, 2019 | Leave a Comment
City College of New York graduate researchers are reporting two breakthroughs with the successful demonstration of an LED (light-emitting diode) based on half-light half-matter quasiparticles in atomically thin materials. This is also the first successful test of an electrically driven light emitter using atomically thin semiconductors embedded in a light trapping structure (optical cavity). The […]

Perovskite Potential Grows For Use In LEDs
August 28, 2019 | Leave a Comment
Tokyo Institute of Technology scientists have discovered a new strategy to design incredibly efficient perovskite-based LEDs with record-setting brightness by leveraging the quantum confinement effect. Several techniques for generation of light from electricity have been developed over the years. Devices that can emit light when an electric current is applied, are referred to as electroluminescent […]

New High Efficiency Quantum Dot White LEDs
July 18, 2018 | Leave a Comment
Researchers at Koç University, Turkey, have demonstrated nanomaterial-based white-light-emitting diodes (LEDs) that exhibit a record luminous efficiency of 105 lumens per watt. Luminous efficiency is a measure of how well a light source uses power to generate light. With further development, the new LEDs could reach efficiencies over 200 lumens per watt, making them a […]
