Research on Light Emission From Black Phosphorus Hints at New Applications

Recent research by Lab scientists on black phosphorus (BP) – a material of interest for its electronic properties – reveals a tantalizing capability for light emission at the BP surface. It turns out that extremely thin layers of BP can be stimulated to emit useful quantities of light in specific wavelengths. Their findings emphasize the unique material characteristics of layered materials for novel optoelectronic applications such as light-emitting devices and photodetectors. Potential applications include night vision, gas sensing, and spectroscopy technologies.
