Optical Properties and Structure of Copper (II) Phthalocyanine(CuPc) Organic Thin Film Grown by Electron --Beam Evaporation Technique

Copper (II) phthalocyanine (CuPc) thin films were grown by electron beam evaporation technique with various substrate temperatures. Crystalline of CuPc thin films was investigated by X-ray diffraction (XRD) spectroscopy. Diffraction pattern exhibit high quality crystalline films as monoclinic α-phase structure. Surface morphology of CuPc thin films was characterized by field emission electron microscope (FE-SEM) and the films grown with 150 °C substrate temperature illustrated nanorod-like structure. Absorption spectra were obtained by UV/visible spectroscopy, revealed to Q-band and B-band. The transition energy of CuPc was characterized by photoreflectance spectroscopy (PR) correspond to an absorption peak of Q-band.
