Prof. Dr. Rubén Costa et. al., ARTIBLED | Paper | 05.11.2020

White light-emitting diodes (WLEDs) consist of a blue-light emitting chip that is covered with yellow-emitting inorganic phosphors based on rare-earth or toxic materials that are regulated by a few countries. Indeed, they are one of the most critical bottlenecks when trying to ensure the sustainable development of WLEDs.

In this context, several groups have focused on developing cheap and environmentally friendly organic phosphors based on polymers, small molecules, complexes, etc. ARTIBLED is a European FET-OPEN initiative that aims at advancing organic phosphors based on fluorescent proteins as emitters and artificial or biogenic polymers as a packaging matrix. This will lead to a new class of color down-converting filters or biogenic phosphors for the next generation of sustainable WLEDs.

Herein, Dr. Rubén D. Costa and his colleagues, Dr. Cortajarena, Dr. Coto, Dr. Barolo, Dr. Ghersi, and Dr. Oberdorfer provide an overview of ARTIBLED, highlighting the recent results in the development of the first devices, based on fully biogenic phosphors.
