<p>The invention relates to a material with light-emitting properties sensitive to oxygen concentration in fluid media, as a polymeric film meant for the assessment of partial pressure in fluid media. According to the invention, the material is characterized in that it is a polymer, such as polystyrene or polyacrylonitrile, additivated with 0.1...4% fluorescent dye with emission within the visible range and excitation within the polymer light-emission range, such as a xanthenic dye.</p> |
