A dual-phase architecture for efficient amplified spontaneous emission in lead iodide perovskites

Author affiliations

Abstract

Multi-particle Auger interactions are one of the major intrinsic limiting factors for lasing applications of lead halide perovskites. In this communication, we report a possible way to tackle this problem by investigating the transfer of the photo-excited population to radiative defect inclusions using transient absorption (TA) spectroscopy. We demonstrate a reduction of the threshold of amplified spontaneous emission (ASE) in the presence of an efficient transfer.
