Researchers from the University of Central Florida have developed a new technique to detect long-wave infrared photons of different wavelengths based on a nanopatterned graphene. "No present cooled or uncooled detectors offer such dynamic spectral tunability and ultrafast response," said Debashis Chanda, the scientist who led this study. "This demonstration underscores the potential of engineered monolayer graphene [long-wave infrared] detectors operating at room temperature, offering high sensitivity as well as dynamic spectral tunability for spectroscopic imaging." The new detection and imaging technique will have applications in analyzing materials by their spectral properties, or spectroscopic imaging, as well as thermal imaging applications.
