## General Notes
- Data are provided in plain text formats (.txt, .dat) and presentation files (.pptx) for direct analysis.  
- Most spectra are normalized unless otherwise specified.  
- Decay times were extracted using multi‑exponential fits convolved with the instrumental response function.  
- Variable‑temperature measurements were performed using cryostat systems.  
- Recommended software for data treatment and visualization: OriginLab and Microsoft Office.
