Abstract
The present disclosure relates to an optochemical sensor element, comprising: a substrate layer having a first substrate side facing toward a measuring medium and a second substrate side opposite the first substrate side; a functional layer arranged on the first substrate side and is subdivided into functional segments separate from one another, wherein a first functional segment has a second reference dye and a second functional segment has an indicator dye, wherein the second reference dye comprises an organic material and is insensitive to oxygen, and is suitable to emit a second luminescence signal upon stimulation with a first stimulation signal, wherein the indicator dye comprises an organic material and is sensitive to oxygen, and is suitable to emit a third luminescence signal upon stimulation with the first stimulation signal, wherein the substrate layer is transparent to the stimulation signal and to the second and third luminescence signals.
