Lead-free Perovskite for Ultraviolet micro-LEDs based White-Light Communication

Despite growing interest in lead-halide perovskites for visible-light communication (VLC), the health concerns associated with lead hinder their widespread application. Herein, we demonstrate for the first time a lead-free perovskite phosphor-based VLC link using an ultraviolet-micro-LED, achieving 84.9 CRI, 4115-K CCT, and 1.5-Mb/s data rate.
