Abstract
:
Electrical conductivity measurements of pyronine G(Y) were performed as a function of both temperature (303-443 K) and frequency (50 Hz-550 kHz). The frequency dependence of ac conductivity is well represented by the form ω8. The values of exponent, (s) decrease from 0.98 at 303 K to 0.67 at 403 K. The temperature dependence of both ac electrical conductivity and the exponent (s) reveals that the ac conduction is due to the correlated barrier hopping (CBH). The dielectric constant, ε1 (ω) and dialectic loss, ε2(ω), have been determined for bulk pyronine G(Y). Both ε1(ω) and ε2(ω) decrease by increasing frequency and increase by increasing temperature.
