4.2: Invited Paper: CsPbBr3 perovskite quantum‐dot paper exhibiting highest 3‐dB bandwidthand realizing flexible white‐light system for visible‐light communication

Abstract

We propose a flexible white-light system for high-speed visiblelight communication (VLC) applications, consisting of a semipolar blue InGaN/GaN single-quantum-well micro-lightemitting diode (LED) on a flexible substrate pumping green CsPbBr3 perovskite quantum-dot (PQD) paper in nanostructure form and red CdSe QD paper. The highest bandwidth for CsPbBr3 PQD paper, 229 MHz, is achieved with a blue micro-LED pumping source, this is very promising for VLC application.
