Abstract
One‐dimensional high‐quality CdS/poly(ethylene oxide) (PEO) hybrid nanoparticle‐polymer fibers were fabricated by an electrospinning method, followed by self‐assemble technologies with co‐fed H~2~S atmosphere at 60 °C. The structural and spectral information of the resulting hybrid nanofibers was characterized by field emission scanning electron microscopy, transmission electron microscopy, X‐ray photoelectron spectroscopy and X‐ray diffractometer. The diameters of CdS/PEO hybrid nanofibers ranged from 90 to 200 nm and the average dimension of CdS nanoparticle within fibers from 4 to 12 nm. An interesting aspect of the CdS/PEO nanofibers shown in photoluminescence spectra and fluorescence images is that the fluorescence peaks of CdS/PEO were shifted along with changing the mass ratio of CdS/Poly(ethylene oxide), and consequently the size and phase of nanocrystal CdS.
