In this article we have reported the nano structure formation in ZincPhthalocyanine (ZnPc) thin films coated on glass substrates by thermal evaporation method. The structure of the films was analyzed by an X-ray diffractometer (using Cu Kα radiation with λ = 1.5418 Å). It reveals that the vacuum evaporated ZnPc thin films are having nano particles in its structure. It is confirmed by the scanning electron microscopy (SEM), X-ray diffraction (XRD) and optical absorption studies. The results of the XRD, SEM and AFM studies have been discussed in this article. A metastable α to the stable β-phase transformation has been observed when the films are coated at higher substrate temperatures. The core structure of the ZnPc macrocycle is formed by four isoindole units endowing the molecule with a two-dimensional conjugated π electron system.
