| Sumario: | A new structural nanocomposite (NC) based on oligomer poly(N-epoxypropyl)carbazole (PEPC) and copper phthalocyanine (CuPc) nanocrystals on a glass substrate are prepared by casting and droplet methods under normal conditions (room temperature, atmospheric pressure). Thin films of the PEPC/CuPc nanocomposite are characterized by visible optical, infrared (FT-IR), and photoluminescence (PL) spectra. The observed FT-IR bands are assigned to vibration modes of molecules and nanocrystals of CuPc on the basis of their symmetry. The optical spectra of PEPC/CuPc nanocomposites films show three main absorption bands attributed to CuPc, one band positioned at 1.46 eV, another one located at 2.02 eV, which is known as the π→ π* transitions in Q-bands and the π→ π* transitions of Soret B-band which was located at 3.02 eV. The effect of irradiation with ultraviolet (UV) light on the optical properties is studied. |
