  • Luminescence-optical method and sensor layer for quantitative determination of at least one chemical component of a gaseous or liquid sample
    Patent number: 6046055
    Abstract: In a sensor layer for quantitative determination of at least one chemical component in a gaseous or liquid sample medium containing a chromophore which is directly or indirectly responsive to the component being determined by changing its absorption spectrum, and a luminophore which is not responsive to the component being determined, where there is an at least partial overlap between the emission spectrum of the luminophore and the absorption spectrum of the chromophore, and where the energy transfer between luminophore and chromophore produces a measurable change in at least one luminescence characteristic of the luminophore, the luminophore L and the chromophore .GAMMA. are ionic substances with differing electrical charges, which are incorporated in a matrix material that is permeable to the chemical component being determined.
    Type: Grant
