Paper Abstract

In the talk I will focus on the optical properties of lead halide perovskites and their dependence on the amount of excess PbI2. I shall first address that, at low temperature, it is possible to optically and reversibly induce a phase change from the orthorhomic to the tetragonal phase. By exploiting amplified spontaneous emission (ASE) from these phases, fully optical read-write-erase cycles can be conducted. I shall then elaborate on how and why the photoluminescence features are modified in the presence of excess PbI2.
