Kiel-LED team’s artificial solid fog creates ‘pleasant’ laser light

Aerobornitride is a highly porous material made of white graphene enabling new laser light applications.

An international research team led by Kiel University, Germany, has developed an extremely porous material made of “white graphene“, which they say promises new laser light applications.

With a porosity of 99.99 %, the material, described as a “solid fog”, consists practically only of air, making it one of the lightest materials in the world. Aerobornitride is the name of the material developed by the Kiel-led. The scientists say they assume that they have created “a central basis for bringing laser light into a broad application range”.

Based on a boron-nitrogen compound, this three-dimensional nanostructure scatters light very strongly while hardly absorbing it. Irradiated with a laser, the new material emits uniform lighting, which, depending on the type of laser, is much more efficient and powerful than LED light, says. Thus, lamps for car headlights, projectors or room lighting with laser light could become smaller and brighter in the future.

The research team presents their results in Nature Communications (March 18 issue). The project is part of the Europe-wide research initiative Graphene Flagship, which involves around 150 research from science and industry sectors in 23 countries.
