A novel route to synthesize CdS quantum dots on the surface of silk fibers via γ-radiation

摘要

CdS quantum dots (QDs) were successfully synthesized on the surface of silk fibers via γ-ray irradiation. Scanning electron microscope (SEM) measurement revealed that the particles on the silk fibers were less than 15nm in diameter. The energy dispersion spectrum (EDS), X-ray diffraction (XRD), laser scanning confocal microscope (LSCM) were also used to identify and investigate the properties of products. Moreover, a mechanism for the formation of CdS QDs on silk fibers under γ-radiation was generally discussed. The resulting silk fibers coated with CdS QDs might be useful as smart structural fabrics in a range of applications.
