High Optical Gain in Stable MOF-Derived Composite Films Based on Perovskite Nanocrystals.
Metal halide perovskite nanocrystals hold great promise for low-cost optoelectronic and lasing applications, yet their integration into composite films is limited by poor stability under high excitation. We present a strategy to fabricate stable, ligand-free perovskite nanocrystal-based composites by combining lead-bas...
