Abstract
An optical sensor is described for determining the concentration of a gas in gas mixtures, which can especially be used for determining the carbon monoxide content of the air. It includes a radiation source, a sensitive layer positioned on a translucent substrate, and a detector. The sensitive layer of the sensor contains a transition metal compound which forms a transition metal complex with the gas to be determined.
