- Additional information
- We demonstrate a three-dimensional foam-like light diffuser consisting of a semi-transparent web of randomly arranged and interconnected hollow microtubes of hexagonal boron nitride. The material acts like an artificial fog, able to efficiently convert directional laser beams into a luminous source that scatters light in all directions, thereby withstanding ~10 times the irradiance level of remote phosphors. This new approach can unleash the potential of lasers for high-brightness lighting applications, such as automotive headlights and projection technology. Indeed this technology has already attracted a lot of interest from related companies and new collaborations and grants are planned.
