Claim 8:
9. A sensor, comprising:
a first polymer-luminescent compound configured to produce a first luminescent signal in the presence of a first analyte, the first polymer-luminescent compound including a first polymer and a fluorescent dye configured to emit light in an emission spectrum in response to being excited with light having an excitation frequency; and
a second polymer-luminescent sensing compound configured to produce a second luminescent signal in the presence of a second analyte that has a spectrum that overlaps a spectrum of the first luminescent signal, the second polymer-luminescent compound including a second polymer and the fluorescent dye, at least one of the first polymer or the second polymer configured to alter temporal characteristics of the fluorescent dye such that the second luminescent signal has a longer lifetime than the first luminescent signal.
