En ny form for hvid lysdiode baseret på fluorescerende silicium-karbid (LEDSiC)

Light-emitting diodes (LEDs) light source is emerging as the future market leader in both indoor and outdoor lighting due to its high energy efficiency, good light quality, long lifetime, and good technical functionality like being a transmitter for visible light communication. This project is going to explore a new type of white LED, which uses fluorescent silicon carbide (f-SiC) as the wavelength conversion material. Compared to the widely used phosphors, f-SiC only contains earth-abundant material, is very robust, and a better substrate than Sapphire for the epitaxial GaN growth on top. Therefore, the new white LED based on f-SiC is going to further reduce the energy consumption and CO2 emission. In this project, the full potential of this new type of LED will be explored in different levels of materials, devices and modules oriented for applications in general lighting and visible light coummunication through the collaboration of top scientists from Europe and China, with involvement of industrial partners. It is expected that the new f-SiC LED will promote the adoption of the LED technology.
