“…Glasses with greater chemical complexity will also lead to increased . A distribution of anionic sites contributes to the DAE, and quench rates are known to strongly influence speciation in glasses [18]. Further, the use of multiple charge carriers will increase the width of the DAE, and the quadratic deviation from Arrhenius behavior observed in Ref.…”

Previously observed non-Arrhenius behavior in fast ion conducting glasses [Phys. Rev. Lett. 76, 70 (1996)] occurs at temperatures near the glass transition temperature, Tg, and is attributed to changes in the ion mobility due to ion trapping mechanisms that diminish the conductivity and result in a decreasing conductivity with increasing temperature. It is intuitive that disorder in glass will also result in a distribution of the activation energies (DAE) for ion conduction, which should increase the conductivity with increasing temperature, yet this has not been identified in the literature. In this paper, a series of high precision ionic conductivity measurements are reported for 0.5Na2S + 0.5] glasses with compositions ranging from 0 ≤ x ≤ 1. The impact of the cation site disorder on the activation energy is identified and explained using a DAE model. The absence of the non-Arrhenius behavior in other glasses is explained and it is predicted which glasses are expected to accentuate the DAE effect on the ionic conductivity.

“…Another useful approach to determining the effects of temperature on glass structure above T g is to vary the fictive temperature (T f ) of the glass by cooling samples at different rates, or by annealing the glasses at different temperatures within the transition range. This method has been successfully used for a variety of silicates [16], aluminosilicates [17,18], and boron-containing glasses [19][20][21][22][23][24]. The advantage of this approach is that the characterization experiments are performed at ambient temperatures where the structural changes can be quantified more accurately with thermal noise being reduced.…”

Since the physical properties and network structure of glass depend on the quenching process from the supercooled liquid state, it is expected that the luminescence of doped activators will also be dominated by the preparation condition. Here, we have investigated the structural and luminescent properties of 0.5SnO-24.5SrO-75B 2 O 3 (SSB) glasses prepared under different preparation conditions. The X-ray-induced luminescences, such as scintillation, thermally stimulated luminescence, and optically stimulated luminescence, of the SSB glasses are affected by the cooling process with different rates of change. For the present SSB glasses, we have found that the rapid cooling process is effective for attaining high luminescent intensities in all measurements.
