Claim:
1. A quantum dot-polymer nanocomposite sensor array for chemical vapor sensing comprising an array of sensors for detecting vapors of a chemical analyte from a predetermined group of chemical analytes, the array of sensors comprising a plurality of sensors, each sensor being formed by a nanocomposite film including a plurality of fluorescent quantum dots (QDs) and a polymer that is responsive to at least one of the chemical analytes, wherein a different polymer is selected for each of the sensors, the plurality of sensors being disposed on a substrate for impingement by an excitation light source, wherein responsive to exposure to a vapor of any one of the chemical analytes the combined fluorescence response of the plurality of sensors identifies which chemical analyte from the predetermined group of chemical analytes is present.
