White light-emitting diodes(WLEDs) with a hybrid poly N-vinylcarbazole(PVK) and poly(methyl methacrylate)(PMMA) polymer and ZnO quantum dots(QDs) were fabricated by a spin-coating technique. Transmission electron microscopy images showed that the ZnO QDs were predominantly distributed at the circumference of the surface of the PVK polymer. Electroluminescence spectra for hybrid polymer-QD WLEDs showed a broad peak around 600nm. The Commission Internationale de I'Eclairage chromaticity coordinates of the WLEDs fabricated utilizing hybrid polymer-QD WLEDs at 10V were (0.39, 0.41), indicative of a white emission. The luminescence mechanisms of the WLEDs are described.
