Through technological advances, light-emitting diode (LED)-based systems have been commercialized and are now widely used in applications such as large displays, traffic lights, indoor and street lighting, automobiles, cell phones, and liquid-crystal displays [1–3]. Recently, white-light-emitting materials have attracted considerable attention owing to their potential use in LEDs, lighting, communications, and, especially, flexible display devices. White-light systems based on micro-LEDs and color converters such as quantum dots (QDs) are becoming more prominent in visible-light communication (VLC) applications. Furthermore, organic optoelectronic components are now being used in VLC systems because they are cheaper and more environmentally friendly, portable, and flexible than traditional silicon-based devices; moreover, they can be mass-produced [4–9]. Application of organic optoelectronic components to VLC systems will allow such systems to be incorporated into wearable fabrics and industrial products.
