Abstract

Optoelectronic light-emitting diode-photodiode pairs based on multicomponent GaInAsSb and InAsSbP solid solutions have been researched and developed. Such pairs are able to detect absorption bands of water and gases belonging to the spectral range 1.8 - 4.8 micrometers (H2O, CO, CO2, H2S, N2O, CH4, etc.). Two-wavelength models of a new type of optical moisture meter and a methane meter was fabricated using the developed LEDs and high-efficiency photodiodes.
