Abstract
The family of solution-processed tin-based perovskites is demonstrated as a new and superior near-infrared gain medium. Due to the large electron-hole bimolecular recombination associated with tin and the reduced trap density with SnF<sub>2</sub> treatment, these lead-free "green" perovskites yield stable coherent light emission extending to ≈1 μm at strikingly low thresholds.
