ABSTRACT:
A luminescent layer for use in apparatus for determining the oxygen concentration in gases, fluids and tissues by measuring the decrease in the light emission of a luminescent surface irradiated with an excitation light of a certain wavelength, where the luminescent dye forms a homogeneous mixture with the light-transparent layer substance, in which case the surface may also have a fine-grained structure.
