Fabrication and Characterization of Cellulose Acetate Ultrafine Fibers Containing CdTe Quantum Dots by Electrospinning

Article Preview

Abstract:

Aqueous CdTe quantum dots(QDs) with different colors were synthesized. Fluorescence spectroscopy analysis showed that synthesized CdTe QDs possessed narrow size distribution. TEM image indicated that the average size of CdTe QDs was 4nm. Fluorescent fibers were prepared by electrospinning mixed solution of CdTe QDs and CA. SEM and TEM photographs showed that the diameters of fibers were 300-700nm, QDs were well dispersed in CA fibers. Fluorescence micrograph showed the fluorescence color and brightness of QDs were not significantly changed after compounding QDs into fibers. The addition of QDs resulted in improvement of crystallinity of the composite fibers by XRD observation.
