Abstract
A fluorescent sensor for the detection of gas compositions has a carrier substrate and a fluorescent layer. The carrier substrate and fluorescent layer consists of a gas-permeable polymer matrix with an embedded fluorescent dye. A diffusion layer of gas-permeable ceramics and/or polymers is arranged over the fluorescent layer and is adapted to cause a time delay of the gas diffusion from a detected-environment to the fluorescent layer and from the fluorescent layer to a detected-environment.

10. A fluorescent sensor for the detection of gas compositions comprising:
-
a carrier substrate and a fluorescent layer applied thereto, the fluorescent layer consisting essentially of a gas-permeable polymer matrix with an embedded fluorescent dye, wherein a diffusion layer of gas-permeable comprising at least one of ceramics and polymers is arranged over the fluorescent layer, the diffusion layer being adapted such that it causes a time delay of gas diffusion from the detected-environment to the fluorescent layer, and the diffusion layer being adapted such that it causes a time delay of gas diffusion from the fluorescent layer to the detected-environment. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
