Abstract
A sensor material of the type comprising a long-decay photoluminescent, protonable dye embedded in a suitable polymeric matrix, is used for generating a specific optical response to two different analytes present in a sample, thus allowing selective determination of the two analytes in the sample. Also described is a method for the simultaneous sensing of a first and second analyte in a sample. The method comprises the steps of irradiating a sensor material of the type comprising a long-decay photoluminescent protonable dye embedded in a suitable polymeric matrix with light of one or two wavelengths, determining photoluminescence intensity and lifetime signals originating from the sensor, and correlating the photoluminescence intensity signal with a concentration of the first analyte and the photoluminescence lifetime signal(s) with the concentration of the second analyte.
