A glass matrix with chemical composition of P2O5-ZnO-Na2O-Al2O3-CuO glasses has been investigated. The frequency and composition dependencies of the dielectric parameters are discussed and analyzed for insight into the dielectric properties of these glasses in an applied AC electric field of frequencies extending from 1.05 to 100 kHz. The ac conductivity measurements exhibit the coexistence of electronic to the electron from Cu+ to Cu2+ ions, and ionic on the mobility of sodium ions.
