This paper examines the prospects of using semiconductor layered A3B6 type-photovoltaic cells and the photoresistors as receptors for quantitative and qualitative measurements of carbon oxides. Carbon compounds in gaseous state form absorption bands of electromagnetic radiation in a wide range of spectrum (200-100 000 cm-1). The light absorbed or emitted in these bands at the excitations with ionizing radiation (X, Y) or strong electric fields contain direct information about the concentration

Fundamental absorption bands of CO, CO2 and NC have the edge of band at the border of ultraviolet-vacuum, while the emission bands d cover their full range of wave numbers from 45000 cm-1 to 10000 cm-1. Two types of radiation receptors from lamellar semiconductor type photosensitive in this spectral range are studied.
