Abstract
The optical, electrical and acoustical properties of a polymer solution based on polyvinyl
pyrrolidone (PVP) doped with different concentration of cupric sulphate (CuSO
4
) were studied.UVVIS spectroscopy results reflected that absorption increases in asymmetric manner and the
absorption peak showed red shift with increasing Cu ions concentration. The optical band gap
(direct and indirect) was found to decrease with increase in Cu ions concentration in the polymer
due to increase in the density of localized states in the band-gap.The value of Urbach energy is
also evaluated from the transmission spectra and the activation energies are also evaluated
from the conductivity measurements and found to decrease with the increase in the concentration
of Cu ion in the PVP. The ultrasonic velocity and surface tension are increased while the
adiabatic compressibility, acoustic impedance and intermolecular free length decreases with
increase in the concentration of CuSO
4
in the polymer PVP.
