| 英文摘要 | Lead-free halide double perovskites (DPs) have been proposed as stable and promising alternatives to lead halide perovskites.Understanding the structural-optical properties of halide DPs isimportant for their applications. In this study, Cs2AgInCl6DPnanocrystals, with a direct band gap, were synthesized and studied.Because of a strong electron-phonon coupling leading to exciton self-trapping, a broad emission with a large Stokes shift of Cs2AgInCl6DPnanocrystals is observed. We observed an abnormal blue-shifted emissionaccompanied by a red-shifted direct absorption edge because of thereduced electron-phonon coupling under compression in the cubic phaseCs2AgInCl6DP nanocrystals. Our study clarified the basic structural-optical correlation of halide DPs and may promote their application in related fields |
