The thermally induced increase in optically stimulated luminescence of super-luminous Sr₄Al₁₄O₂₅:Eu,Dy is reported. To isolate this thermal assistance to emission, which is otherwise obscured by high intensity transient emissions, stimulation was done using 870 nm infrared light. The optically stimulated luminescence intensity measured between 20 and 200 °C goes through a peak. The profile is reproducible and is independent of whether the measurements are made with the temperature increasing or decreasing. The initial increase in signal is ascribed to thermal assistance and the subsequent decrease is due to thermal quenching. The activation energy of thermal assistance was determined as $0.30\pm 0.01$ eV. The corresponding value for the activation energy for thermal quenching is also reported as are methods for determining these parameters from the temperature dependence of the luminescence. The thermal assistance effect is explained with reference to a configurational coordinate model.

据报道，热激发的超发光Sr ₄ Al ₁₄ O ₂₅：Eu，Dy的光激发发光增加。为了将这种热辅助与发射隔离开来，否则会被高强度的瞬态发射所遮挡，使用870 nm红外光进行了刺激。在20至200°C之间测得的光激发发光强度穿过一个峰值。该轮廓是可复制的，并且与温度是随温度升高还是降低而进行测量无关。信号的最初增加归因于热辅助，随后的减少归因于热淬火。热辅助的活化能确定为$0.30\pm 0.01$eV。还报道了用于热淬灭的活化能的相应值，以及根据发光的温度依赖性确定这些参数的方法。参照构造坐标模型来说明热辅助效果。
