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 […]

An All New Light Emitting Diode

April 25, 2019 | Leave a Comment

Scientists at TU Wien (Vienna) have now succeeded in using exotic bound states of particles to create a novel kind of light-emitting diode. In ultra thin materials, exotic bound states of particles can be created which are then converted into light. When particles bond in free space, they normally create atoms or molecules. However, much […]

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 […]
