Abstract
A sensor element for an optochemical sensor includes: a luminescence indicator, whose luminescence can be quenched with oxygen; and scavenger units to deactivate singlet oxygen, forming a chemical reaction product by reacting with singlet oxygen, wherein the scavenger units are selected to be recovered by a decomposition reaction induced thermally, photochemically or by a pressure increase of the chemical reaction product formed by the reaction with singlet oxygen.
Claims14
A sensor element for an optochemical sensor, the sensor element comprising:
- a luminescence indicator, whose luminescence can be quenched with oxygen;
- and
- scavenger units configured to deactivate singlet oxygen via forming a chemical reaction product by reacting with singlet oxygen,
- wherein the scavenger units are selected to be recovered by a decomposition reaction, which decomposition reaction is induced thermally, photochemically, or by a pressure increase of the chemical reaction product formed by the reaction with singlet oxygen.
