properties of 2D CsPb2Br5 and its ion exchanged halides. Recently the root cause of such a behavior has been revealed [1] by using a combination of techniques (Raman and Photoluminiscence, PL), one statitc and the other dynamic with variable hydrostatic pressure. It has been posible to correlate PL with the structure and distinguish different mechanisms of PL from point defect versus extended structures. In that
