Electrical, dielectric, and optical properties of Sb2O3?Li2O?MoO3 glasses
Original language description
Temperature and frequency dependencies of DC and AC conductivities, dielectric response, static permittivity, optical absorption edge, infrared absorption spectrum, density, and temperatures of glass transition and crystallization for lithium molybdenum-antimonite glasses, (80-x)Sb2O3-20Li(2)O-xMoO(3), where x = 0-40, are measured and discussed. The DC conductivity increases with increasing concentration of MoO3. At 150 degrees C, it ranges from 5 x 10(-11) S/m up to 3 x 10(-8) S/m. Polaron hopping between Mo5+ and Mo6+ ions contributes, probably, to the DC conductivity. Ionic conductivity by Li+ ions is also present. The conduction activation energy monotonously decreases from 1.15 eV, at x = 5, down to 0.91 eV, at x = 40. In all glasses with x> 0, the conduction activation energy is close to a half of the indirect allowed optical gap. The pre-exponential factor, sigma(0), goes through a sharp maximum close to the composition (x = 20) with both the highest glass transition temperature
