The one‐pot synthesis of nanocomposites of a conductive poly( N ‐vinylcarbazole) (PVK) with CdS, Ag, Pd 50 –Ag 50 , and Pt 50 –Ru 50 nanoparticles was performed with γ irradiation in a tetrahydrofuran–water mixture (3/1 vol %). For comparison, the CdS, Ag, Pd 50 –Ag 50 , and Pt 50 –Ru 50 nanoparticles were also prepared with γ irradiation with polyvinylpyrrolidone as a stabilizer. Ultraviolet–visible spectroscopy, transmission electron microscopy, X‐ray diffraction analysis, and photoluminescence spectroscopy were used for the characterization of CdS, Ag, Pd 50 –Ag 50 , and Pt 50 –Ru 50 nanoparticles and nanocomposites of PVK with CdS, Ag, Pd 50 –Ag 50 , and Pt 50 –Ru 50 nanoparticles. The absorption spectrum of the CdS‐nanoparticle‐based composite revealed a quantum confinement effect. The emission spectrum of the composite with CdS nanoparticles and PVK indicated the block effect of PVK for surface recombination. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 100: 1809–1815, 2006
