Abstract
Here we present a simple technique for copper (II) detection in aqueous solutions by luminescent dye doped polymeric film. In this study the photoluminescent dye lumocupferon was first embedded in thin films of polysaccharide chitosan. The sensor response is forming by quenching the dye luminescence. This technique can offer a rapid detection of Cu2+ with a dynamic range up to 350 μM.
