Temperature-dependent photoluminescence spectra of thioflavin T and movies of photoluminescence on a cold, rotating copper surface

These are data from experiments in which the rapid cooling of a jet of glycerol/water upon striking the surface of a cold, rotating copper plate was monitored by recording movies of photoluminescence from thioflavin T (ThT) dye that was dissolved in the glycerol/water mixture. The data set includes emission spectra of ThT in glycerol/water at temperatures from 80 K to 300 K, showing the strong dependence of photoluminescence on temperature. The data set also includes segments of the movies that were analyzed to determine cooling rates and the dependence of the cooling rate on the copper surface velocity at the point where the glycerol/water jet strikes the surface. Details of the data are given in the READ_ME.txt file.本数据集源自一组实验数据：甘油/水射流撞击冷态旋转铜板表面后的快速冷却过程，通过记录溶解于该混合液中的硫黄素T（thioflavin T, ThT）染料的光致发光（photoluminescence）影片进行监测。数据集包含80 K至300 K温度范围内甘油/水溶液中ThT的发射光谱，展现出光致发光对温度的显著依赖性。此外，数据集还包含经分析的影片片段，用于计算冷却速率，以及冷却速率随甘油/水射流撞击点处铜板表面线速度的变化关系。数据集的详细说明请参见READ_ME.txt文件。
