Scientists from the University of Birmingham and the University of Cambridge have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems.
, the team converted low-energy MIR photons into high-energy visible photons using molecular emitters. The new innovation has the capability to help scientists detect MIR and perform spectroscopy at a single-molecule level, at room temperature.
"At room temperature, these springs are in random motion which means that a major challenge in detecting mid-infrared light is avoiding this thermal noise. Modern detectors rely on cooledthat are energy-intensive and bulky, but our research presents a new and exicting way to detect this light at room temperature."
Dr. Chikkaraddy continued,"The most challenging aspect was to bring together three widely different length scales—the visible wavelength which are hundreds of nanometers, molecular vibrations which are less than a nanometer, and the mid-infrared wavelengths which are ten thousand nanometers—into a single platform and combine them effectively."
This breakthrough has the ability to deepen understanding of complex systems, and opens the gateway to infrared-active molecular vibrations, which are typically inaccessible at the single-molecule level. But MIRVAL could prove beneficial in a number of fields, beyond pure scientific research.
