In an opto-chemical sensor, comprising a sensor layer attached to a carrier and formed from spun nano fibres doped with a luminescent dyestuff, wherein the emission property of said sensor layer can be changed in a gas or liquid phase after excitation with electromagnetic radiation by substances which are to be detected such as O 2 , CO 2 , lactate, glucose, NH 3 , SO 2 , H 2 O 2 , nitrogen oxides, halogenated hydrocarbons and ions or measurement variables which are to be determined, such as the pH-value, moisture and temperature in a gas or liquid phase, the sensor layer is formed from nano fibres with a diameter between 50 nm and 1000 nm and the nano fibres are doped with at least one luminescent dyestuff selected from the group consisting of metal porphyrins, benzoporphyrins, azabenzoporphyrins, napthoporphyrins, phthalocyanines, polycyclic aromatic hydrocarbons, particularly perylenes, perylene diimines, pyrenes; xanthene dyestuffs, azo dyestuffs, bodipy dyestuffs, azabodipy dyestuffs, cyanine dyestuffs, metal-ligand complex dyestuffs, particularly bipyridines, bipyridyls, phenantrolines, coumarins and acetyl acetonates of ruthenium and iridium; acridine dyestuffs, oxazin dyestuffs, coumarins, azaannulenes, squarines, 8-hydroxyquinolines, polymethines, luminescent nano particles, such as quantum dots, nano crystals; carbostyryls, terbium complexes, inorganic phosphors or dyestuffs of the aforementioned classes derivatized or bound to ionophores (e.g. crown ether). |
