Nanocrystals speed up Wi-Fi-emitting LEDs

Communication technologies like Bluetooth and Wi-Fi operate on invisible radio waves, but transmitting data on wavelengths we can see might turn out to be more efficient and secure. Researchers at King Abdullah University of Science and Technology (KAUST) have developed a nanocrystal that helps boost data speeds transmitted through a visible light LED up to 2 Gbps – while pleasantly lighting the room.
