Scientists Develop BioLED Alternative to Phosphors

Craig DiLouie May 25, 2016

A German-Spanish team of scientists is working on a BioLED source made of red, blue and green luminescent proteins in the form of rubber, which is wrapped around a blue or ultraviolet LED to act as the visible light filter instead of a phosphor.

The overall effect is the same as LED but with a lower cost and, perhaps, more sustainability for white-light LEDs, which currently use rare-earth materials such as cerium and yttrium. The researchers also point out that the stable nature of the proteins means the LED device can remain in storage under different environmental conditions while preserving its emission characteristics. They are currently working on improving the material to be more resilient and offer a longer lifetime.
