Midinfrared Light-Emitting Diodes Based on A(3)B(5) Heterostructures in Gas-Analyzer-Equipment Engineering: Potential and Applications in 2014-2018

摘要

Studies published in the period from 2014 to 2018 that are aimed at creating nondispersive and photoacoustic IR gas analyzers with LED radiation sources based on A(3)B(5) heterostructures and operating in a range of wavelengths from 3 to 5 mu m are reviewed. Potential of gas analysis equipment based on the aforementioned LEDs for detecting CO, CO2, methane, and other gases is analyzed.
