B-PHOT researcher professor Nathalie Vermeulen and her team have discovered a very unexpected and far-reaching trait of graphene, a substance that is seen by many as a game-changing material of the future. Graphene is capable of changing the wavelength of light, and their research showed that instead of strong incoming light intensities as typically employed for this purpose, graphene has a better conversion efficiency for low incoming light intensities.
