Abstract

Various concentration of lead (Pb2+) doped ZnO nanocrystalline thin films were prepared by chemical bath
deposition and dielectric constant, dielectric loss and AC conductivity properties were studied as a function of
frequency at different temperatures. The XRD results revealed that prepared nanocrystalline films have wrutzite
structure and the crystallite sizes of doped ZnO increased with increasing Pb2+ concentration. The variation of
AC conductivity (ζac) as function of temperature indicates that the conduction is due to thermally activated
charge carriers. The DC conductivity (ζdc) value of doped ZnO at room temperature has been found to increase
by more than two orders of magnitude from pure ZnO nanocrystalline thin film. The AC electrical conductivity
of doped films is higher than that of pure ZnO film. The observed ζac values are found to be more than ζdc
values
