The book deals with the structural, electrical and non-linear optical properties of metal substituted naphthalocyanine single and composite thin films.Phthalocyanines and naphthalocyanines have been reviewed with details of their molecular structures. The structural properties of the thin films were characterized using the Fourier Transform Infrared spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) which reveal traces of organic compounds within the deposited films.The electrical conductivity of the films at various heat treatment stages shows that SnNc has a better conductivity by 10-50 times that of the earlier reported phthalocyanine thin films and the activation energy is found to increase with annealing temperature.The XRD spectra revealed polycrystalline nature for both annealed and -ray irradiated films. Raman spectra show that the - irradiated films have a higher disorder producing broad and diffuse peaks in comparison to its annealed samples.
