Abstract

Co~3~O~4~/poly(N‐vinylcarbazole) (PNVC) composite with enhanced optical property was synthesized via a simple in situ bulk polymerization of NVC monomers in the presence of Co~3~O~4~ nanoparticles at an elevated temperature. High‐resolution electron microscopic observations showed that the Co~3~O~4~ nanoparticles were coated with uniform nanolayer shells of PNVC. Fourier‐transform infrared (FT‐IR) spectroscopy revealed the presence of strong interactions between the PNVC polymer chains with the Co~3~O~4~ surface in the Co~3~O~4~/PNVC composite. Raman spectroscopic results supported conclusions based on electron microscopy and FT‐IR spectra. The uniform nanolayer coating of PNVC decreases the inherent bulk conductivity of Co~3~O~4~, however, significantly increases the fluorescence property of Co~3~O~4~ nanoparticles.
