Abstract
Novel nano-filament lithium phthalocyanine (LiPc) complexes with different concentrations of Li + ions have been prepared successfully via the urea fusion technique. Spectrophotometric measurements such as XRD and SEM are used to characterize the obtained nano-filament complexes. The behavior of electrical conductivity (DC and AC) for the prepared complexes at frequency range 0.1 KHz – 5 MHz and temperature 298 K ≤ T ≤ 423 K is presented. The conduction mechanism is suggested to be a result of thermal hopping of the activated electrons while at low frequency range the electrons may tunnel through the nanoparticles of LiPc complexes. The activation energies of DC-conductivity were calculated from the Arrhenius plot and ranged from 0.314 eV to 1.243 eV. These values show that the rate of electron transport depends on temperature within these ranges.
