In May 2017 graphene-info.com reported the the Institute of Low Temperature and Structure Research, located in Wroclaw, Poland, developed a new efficient white light source that uses graphene foam excited by a continuous-wave laser. We have seen a demonstration of the technology at IDTechEx 2019 (see video below).
Graphene-info.com recently spoke with Professor Krzysztof Piech who updated the project’s process. Prof. Piech said that the research team received a grant of around $130,000 to develop the technology, and they are expecting to soon receive a $270,000 grant that will enable the production of a series of prototypes. We hope to update once these prototypes can be demonstrated.
The Graphene Light uses a laser that is directed to a graphene foam. The laser opens up a bandgap which results in light emission that ranges from 360nm (UV) or 405nm (visible) to 980nm-1064nm (near-infrared). The researchers say that the light spectrum of this device is similar to the spectrum of the sun.
The National Graphene Association is the main organization and body in the U.S. advocating and promoting the commercialization of graphene. NGA is focused on addressing critical issues such as policy and standards development that will result in effective integration of graphene and graphene-based materials globally. NGA brings together current and future graphene stakeholders — entrepreneurs, companies, researchers, developers and suppliers, investors, venture capitalists, and government agencies — to drive innovation, and to promote and facilitate the commercialization of graphene products and technologies.
