Title: Study of dielectric relaxation process in nanocomposite of Li{sub 2}O−SiO{sub 2} nanoglass-CuO nanoparticles

Dielectric behaviour of a nanocomposite consisting of 23Li{sub 2}O⋅77SiO{sub 2} nanoglass within the pores of compacted CuO nanoparticles was studied. Real and imaginary parts of dielectric permittivity of the material were measured over the temperature range 313 to 363 K. The results indicated a relaxation behaviour. The data were explained by a space charge polarization model developed in the case of a laminar conductor. The activation energy of the relaxation process was in close agreement with that of lithium ion conduction in the nanoglass.
