| Abstract: | Poly(styrene‐block‐4‐vinylpyridine) (PS4VP)–CdS nanocomposites containing different concentrations of CdS were synthesized by an in situ method. Scanning electron microscopy and transmission electron microscopy results indicate that the morphologies of PS4VP–Cd(II) and PS4VP–CdS were controlled by the Cd(II) concentration and the solvent, respectively. The effects of the CdS concentration on the crystal style of CdS in PS4VP–CdS and the photoluminescence (PL) properties of the PS4VP–CdS were also examined. By a comparison of the PL spectra of PS4VP–CdS in solutions, films, and powders, the PL mechanism of PS4VP–CdS was also delivered. The PS4VP–CdS nanocomposite shows potential for application in water‐soluble fluorescence probes. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013 |
