ABSTRACT: Hybrid materials consisting of M(II)Pc (M = Fe, Co,
Ni) particles dispersed in nylon 11 films have been prepared by using a thermal
relaxation technique. The obtained films are characterized by AFM, SEM and TEM,
and their structural composition is determined by IR spectroscopy and EDS. The
M(II)Pc particles are homogeneously distributed in the nylon 11 matrix after
heat treatment. Optical absorption studies of the hybrid films are performed in
the 200 - 1150 nm wavelength range. The band-model theory is applied to determine
the optical parameters for MPc/nylon 11 hybrid films. The optical band gap of
the thin films is determined from the (αhν)1/2 vs. hν plots for indirectly allowing
transitions and comparing with the as-deposited M(II)Pc thin films. The values
of the optical band gap calculated from the absorption spectra, range between
1.07 and 2.7 eV. The electrical conductivity is measured in order to evaluate
the conductivity behavior of these hybrid films.
