When Fluorescent Proteins Meet White Light-Emitting Diodes


Over the last decades, fluorescent proteins (FPs) have been extensively employed for imaging and tracing in cell-biology and medicine. However, their application for lighting devices like light-emitting diodes (LEDs) and lasers has recently started. The interest of FPs lies on their good photoluminescence features (high emission efficiency with a narrow spectrum and a high photon flux saturation), good photostability, low-cost production via bacteria, and eco-friendly recycling. The low stability at high temperatures as well as the need of an aqueous environment have, however, strongly limited their use in optoelectronics. This has recently been circumvented with new coating systems that are paving the way for the entrance of FPs into the LED field. In this minireview, we summarize the first steps done by a few groups towards the development of bio-inspired hybrid white LEDs (Bio-HWLEDs) with a focus on using FPs as color down-converters, highlighting the state-of-the-art and challenges associated to this emerging field.
