1. A sensor, comprising:
a first polymer-luminescent sensing compound including a first polymer and a dye, the first polymer-luminescent compound configured to produce a first luminescent signal in the presence of a first analyte; and
a second polymer-luminescent sensing compound including a second polymer and the dye, the second polymer-luminescent compound configured to produce a second luminescent signal in the presence of a second analyte, a spectrum of the second luminescent signal overlapping a spectrum of the first luminescent signal, the second luminescent signal having a longer luminescent lifetime than the first luminescent signal.
