Preparation and Characterization of Thermally Evaporated Octa Substituted Zinc Phthalocyanine Thin Films
Thin films of Zinc Octakis Octyloxy Phthalocyanine (ZnPcOC8) are prepared at a base pressure of 10 – 5 Torr using Hind Hi-Vac-12A4 thermal evaporation plant. The films are deposited onto precleaned glass substrates kept at room temperature. Absorption spectra of the films are recorded using the Shim...

| description | Thin films of Zinc Octakis Octyloxy Phthalocyanine (ZnPcOC8) are prepared at a base pressure of 10 – 5 Torr using Hind Hi-Vac-12A4 thermal evaporation plant. The films are deposited onto precleaned glass substrates kept at room temperature. Absorption spectra of the films are recorded using the Shimadzu 160A UV-Visible spectrophotometer. The effect of post deposition annealing on the optical constants are studied. The nature of optical transition is found to be direct type. The optical band gap energy of the annealed samples remains almost the same. The invariance of the optical band gap shows the thermal stability of the material for optical applications. The X-ray diffraction analysis of vacuum evaporated films reveals that the crystallinity increases with increase in annealing temperature. The variation of the surface morphology with annealing is also studied using Scanning Electron Micrograph (SEM). |
