Wi-fi from nanocrystal-based lasers
A nanocrystalline material that rapidly makes white light out of blue light has been developed by KAUST researchers (ACS Photonics, “Perovskite Nanocrystals as a Color Converter for Visible Light Communication”). While Wi-Fi and Bluetooth are now well established technologies, there are several advantages gained by shortening the wavelength of the electromagnetic waves used for transmitting … Read more
