Abstract (en)

[origin: CA2653894A1] Fluorescence sensor for detecting gas compositions, said sensor having a carrier substrate (1) and a fluorescent layer (10) which is applied to the l atter and essentially comprises a gas-permeable polymer matrix (2) with a fl uorescent dye (3) embedded in it, wherein a diffusion layer (4) made of gas- permeable ceramics and/or polymers is arranged above the fluorescent layer ( 10), said diffusion layer being adapted in such a manner that it gives rise to a time delay in the diffusion of gas from the environment (5) to be detec ted to the fluorescent layer (10) and vice versa.
