Steady-state and time-resolved emission techniques were employed to study the nonradiative process of Thioflavin-T (ThT) in 1-propanol as a function of temperature. We found that the nonradiative rate, k(nr), decreased by about 3 orders of magnitude when the temperature was lowered to 88 K. We found remarkably good correspondence between the temperature dependence of k(nr) of ThT and the dielectric relaxation times of the 1-propanol solvent.
稳态和时间分辨发射技术被用来研究噻唑橙（ThT）在 1-丙醇中的非辐射过程作为温度的函数。我们发现，当温度降低到 88 K 时，非辐射速率 k(nr) 降低了约 3 个数量级。我们发现 ThT 的 k(nr) 的温度依赖性与 1-丙醇溶剂的介电弛豫时间之间存在非常好的对应关系。
