Beschreibung
Zusammenfassung:	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. Invenţia se referă la un material cu fotoluminescenţă sensibilă la concentraţia oxigenului în medii fluide, sub formă de film polimeric, destinat evaluării presiunii parţiale în medii fluide. Materialul conform invenţiei se caracterizează prin aceea că este un polimer, cum ar fi polistiren sau poliacrilonitril, aditivat cu 0,1...4% colorant fluorescent, cu emisie în domeniul vizibil şi excitare în domeniul emisiei de luminescenţă a polimerului, cum ar fi un colorant xantenic.
