Abstract
A sensing system for quantifying a gaseous species or an analyte in a sample in accordance with one embodiment of the present invention includes a light emitting diode and a detector. The light emitting diode is coupled to a power source and at least a portion of the light emitting diode is coated with a sol-gel-derived film doped with a doping material. The detector is spaced from and substantially across from the portion of the light emitting diode coated with the sol-gel-derived film. The system may include a filter which is located between the light emitting diode and the detector and a processing system which is coupled to the detector for quantifying the amount of a gaseous species or an analyte in a sample based on data from the detector.
