New Light Source can Facilitate a Simplified MIR Fiber-Optic Sensor Device

New Light Source can Facilitate a Simplified MIR Fiber-Optic Sensor Device
Written by AZoSensorsApr 1 2021
A research team of the National Institutes of Natural Sciences, National Institute for Fusion Science and Akita Prefectural University have successfully demonstrated a broadband mid-infrared (MIR) source with a simple configuration.
This light source generates highly-stable broadband MIR beam at 2.5-3.7 μm wavelength range maintaining the brightness owing to its high-beam quality. Such a broadband MIR source facilitates a simplified environmental monitoring system by constructing a MIR fiber-optic sensor, which has the potential for industrial and medical applications.
In the MIR wavelength region, there are many strong absorption lines of molecules due to the change of their rotational and vibrational states. Therefore, by using MIR sources, we have promising opportunities to develop sensitive remote monitoring systems of practical use. ....

Nanographene is flexible, yet stronger than steel. With unique physical and electronic properties, the material consists of carbon molecules only one atom thick arranged in a honeycomb shape. Still early in technological development, current fabrication methods require the addition of substituents to obtain a uniform material. Additive-free methods result in flimsy, breakable fibers until now.
An international team of researchers has developed self-assembling, stable and strong nanographene wires. The results were published on March 24 in
Journal of the American Chemical Society. ....
