University Team Creates World’s Smallest LED

A research team from Zhejiang University’s College of Optical Science and Engineering and Haining International Campus has successfully developed micro- and nano-scale perovskite LEDs (micro-PeLEDs and nano-PeLEDs) reaching a new size limit of 90 nanometers, with minimal efficiency loss in the downsizing process. According to the paper, the team achieved perovskite LED pixels from hundreds of micrometers down to 90 nm—extending well below conventional LED size limits.
