Stable and homogeneous Zinc phthalocyanine (ZnPc) thin films were prepared in a "Hind Hi Vac:" vacuum coating unit (Model No. 12 A4) using thermal evaporation technique. The thicknesses of the films are monitored by a single crystal thickness monitor and crosschecked by air wedge method and it is found to be 725nm.UV-Visible absorption spectra of as-deposited ZnPc thin films are recorded in the wavelength range 200-1000nm.Q band shows Davydov splitting. Transition is found to be direct and allowed. Optical absorption spectra of these films are analysed to get the energy band gaps. The energy band gap is found to be 2.848eV. X-ray diffractograms are recorded for as deposited ZnPc thin films. XRD pattern shows that the deposited film is amorphous.
