06254831 is referenced by 159 patents and cites 78 patents.

Provided is an optical sensor including a support and a detection layer, wherein the detection layer includes:

(a) a luminescent material wherein the luminescence intensity of the luminescent material varies as the amount of an analyte varies;

(b) a reflective material having a highly efficient reflectance of the wavelengths of excitation and of emission of the luminescent material; and

(c) a polymeric binder to support and hold together the luminescent material and the reflective material. Such an optical sensor can be advantageously used in the detection of gaseous, ionic, and nonionic analytes in highly scattering samples. Also provided are methods for the manufacture of such optical sensors.
