A metal halide perovskite (MHP) film is an excellent gain medium for optically pumped lasing. Although high hole and electron mobilities of MHP films would be useful for realizing electrically pumped laser devices, in which high current operation is required, electrical las-ing has never been demonstrated. For future electrical lasing, in this study, we investigated excited-state quenching and lasing behaviors of 1-naphthylmethlamine (NMA)-based MHP films. We found that NMA-based MHP films have less excit-ed-state quenching and, therefore, exhibit a relatively low laser threshold under optical pumping.
