Polymeric solutions containing cadmium selenide quantum dots were electrospun into fibers. Initial characterization using SEM-EDX and fluorescence microscopy showed that the polymer fibers were doped with the quantum dots. Further characterization is being done to determine how the quantum dots are incorporated into the fibers. This characterization includes determining the quantum yield of the quantum dots through fluorescence emission using quinine sulfate as the reference material. Additionally, the fibers were challenged with exposure to headspace vapors of chemicals of interest to see how fluorescence of the quantum dots in the fibers changed with exposure time and sample concentration. Each polymer-doped fiber responded uniquely to the vapors, indicating a potential detection technique that would differentiate between chemicals.
