| contents | Quasi-2D tin iodide perovskites (TIPs) are promising lead-free alternatives for optoelectronic applications, but achieving stable lasing remains challenging due to their limited environmental stability. Here, we report air-stable, room-temperature lasing from quasi-2D TIP microcrystals as small as 4 μm. Incorporation of the organic spacer 5IPA3 significantly enhanced the stability of these materials compared to previously reported TIPs. Lasing was observed from both dielectric (n=4) and plasmonic (n=3 and n=4) TIP microlasers. Under picosecond pumping, lasing was sustained for over 10^8 pump pulses in ambient conditions. These results represent a significant step toward practical photonic applications of tin-based perovskites. |
