The family of 2D Ruddlesden-Popper perovskites is currently attracting great interest of the scientific community as highly promising materials for energy harvesting and light emission applications. Despite the fact that these materials are known since several decades, only recently it has become evident that their optical properties are driven by exciton-phonon coupling which can be controlled by organic spacers. However, the detailed mechanism of this coupling, which often leads to intriguing properties, raises ongoing controversy. The optical properties of these soft semi-conductors cannot be decoupled from their vibrational properties. Therefore, we want to join the long term expertise of LNCMI in optical studies of perovskites and CEMES experience in advanced Raman spectroscopy to gather the complementary information concerning both electron and phonon properties. The electron-phonon coupling will be accurately examined in order to understand mutual dependences between 2D perovskite architecture and their optical properties.
