Time-resolved luminescence image sequences for temperature mapping and calibration in a synthetic porous medium

This dataset contains time-resolved luminescence image sequences acquired during a hot water injection experiment in a two-dimensional porous medium. A subset of 10 time points is provided, corresponding to the temperature maps shown in the manuscript. For each time point, the dataset includes a sequence of 2633 raw image frames used to compute the luminescence decay and infer temperature fields. In addition, the dataset includes luminescence image sequences acquired under uniform thermal conditions at selected temperatures, used for calibration of the lifetime-temperature relationship. Each calibration dataset consists of a sequence of raw image frames acquired under steady temperature conditions. A seperate single dataset of image sequences acquired at room temperature are also provided to assess the pixel-wise relationship between excitation intensity and measured lifetime. The full dataset is not included due to size constraints but is available from the corresponding author upon request.
