Temperature-dependent time-resolved photoluminescence spectral mapping (TRPL-SM) data of an In_0.24Ga_0.76 single quantum well were analyzed using Bayesian inference to estimate the parameters of the photolumnescence decay curves and evaluate them statistically. The fitting function considered both stretched exponential (SE, 0 < β ≤ 1) and compressed exponential (CE, 1 < β < 2) models. Consequently, the shape parameter β was found to vary with emission energy, exhibiting behavior that transitions between CE and SE.Details of the physical interpretation will be presented in the talk.
