Researchers from Germany's Goethe University discovered that graphene doped with boron atoms feature an intensive blue fluorescence - which means that this new material may prove to be useful in OLED devices.
The Boron doping changes the graphene in two ways. First of all, it shifts the fluorescence into the desirable blue spectral range. It also improve the capacity to transport electrons. The new material is reportedly not sensitive to oxygen and moisture, unlike most boron-containing graphenes.
Currently we do not have any information on how useful this material is as a blue OLED emitter - the research did not disclose lifetime and efficiency specifications.
