Thin films of copper phthalocyanine deposited by solution processing methods

Scanning Electron Microscopic Characterization of Copper (II) Phthalocyanine Nanocrystallites Thin Films Deposited on Technologically Important Substrates

Field Emission Scanning Electron Microscopy (FESEM) demonstrates spectacular changes in the morphology of thin films of copper (II) phthalocyanine (CuPc) deposited on gold coated quartz substrates at different substrate temperatures, and on indium tin oxide (ITO) substrates at room temperature followed by post deposition annealing at various temperatures under normal atmosphere. The nature of s...

SrBi2Nb2O9 Thin Films Deposited by Dip Coating Using Aqueous Solution

A new approach for SrBi2Nb2O9 (SBN) thin ®lms synthesis using aqueous solution was successfully experienced. The deposition solution was prepared from Sr±Bi±Nb mixed-citrate solution, requiring no special atmosphere and using common reagents. Films were deposited by dip coating onto Pt/Ti/SiO2/ Si(100) substrates and heat treated at temperatures ranging from 300 to 700 C. The process of formati...

Optical Properties of Copper Phthalocyanine(CuPc)Thin Films

The Anisotropic Dielectric Function for Copper Phthalocyanine Thin Films

Copper phthalocyanine (CuPc) thin films were prepared by organic molecular beam deposition (OMBD) in high vacuum and ultra-high vacuum on passivated Si(111) using β-phase CuPc as source material. The substrates were kept at room temperature during the deposition. The IR peak positions indicate that the films consist mainly of α-phase CuPc, while the relative intensities suggest that the films a...

Spin Exchange Interaction in Substituted Copper Phthalocyanine Crystalline Thin Films

The origins of spin exchange in crystalline thin films of Copper Octabutoxy Phthalocyanine (Cu-OBPc) are investigated using Magnetic Circular Dichroism (MCD) spectroscopy. These studies are made possible by a solution deposition technique which produces highly ordered films with macroscopic grain sizes suitable for optical studies. For temperatures lower than 2 K, the contribution of a specific...
