White LEDs: Ultra‐Efficient and High‐Quality White Light‐Emitting Devices using Fluorescent Proteins in Aqueous Medium (Adv. Mater. Technol. 6/2020)

In article number 2000061, Sedat Nizamoglu and co-workers introduce efficient and eco-friendly white LEDs by integration of fluorescent proteins in their natural aqueous environment onto blue LED chips. The aqueous integration preserves the quantum yield levels of eGFP and mScarlet proteins above 70% in the device architecture and facilitates a high luminous efficiency of 81 lm W–1 with a color rendering index of 83, which is the most efficient eco-friendly white LED reported to date.
