Abstract
The application of room temperature indium LED and photodiode devices, to the detection of nitrogen dioxide, using infrared absorption, is reported. With the photodiodes minimally cooled to -20 °C for improved sensitivity, a resolution of 3 ppm for nitrogen dioxide detection is achieved, using a path length of 4 m. The potential applications of the photodiodes include air pollution monitoring and measuring emissions from power flues and vehicle exhausts.
