Abstract
Cesium based inorganic perovskites represent a very promising alternative to hybrid organic perovskites given their better long-term stability and the impressive radiative yield. Therefore such materials are extremely attracting not only for tandem photovoltaic cells but also for the realization of efficient LEDs and lasers, being possible to cover a spectral range from near ultraviolet (NUV) to near infrared (NIR) depending on the halide composition. Thus the study of the photoluminescence (PL) emission in these materials is very important: in particular the increase of PL lifetimes with temperature and the change on morphology after prolonged laser irradiation in CsPbBr3 nanocrystals (NCs) require further investigation.
