Abstract
Quantum efficiencies of organic-inorganic hybrid lead halide perovskite light-emitting devices (LEDs) have increased significantly, but poor device operational stability still impedes their further development and application. All-inorganic perovskites show better stability than the hybrid counterparts, but the performance of their respective films used in LEDs is limited by the large perovskite grain sizes, which lowers the radiative recombination probability and results in grain boundary related trap states. We realize smooth and pinhole-free, small-grained inorganic perovskite films with improved photoluminescence quantum yield by introducing trifluoroacetate anions to effectively passivate surface defects and control the crystal growth. As a result, efficient green LEDs based on inorganic perovskite films achieve a high current efficiency of 32.0 cd A−1 corresponding to an external quantum efficiency of 10.5%. More importantly, our all-inorganic perovskite LEDs demonstrate a record operational lifetime, with a half-lifetime of over 250 h at an initial luminance of 100 cd m−2. All-inorganic cesium lead bromide perovskite based light-emitting diodes show improved operational stability but the film quality limits their performance. Here Wang et al. use trifluoroacetate anions to passivate defects and achieve excellent device performance and stability.

Abstract
A new Pb(II) complex,[Pb(bp)2(btfa)2] 1, has been synthesized with bathophenanthroline (bp) and benzoyltrifluoroacetone (Hbtfa) and characterized by elemental analysis IR andH1NMR spectroscopy as well as by thermal properties and X-ray crystallography. The coordination number of the Pb(II) ions in 1 is eight, with thePbN4O4coordination polyhedron containing a stereochemically “inactive” electron lone pair with holodirected coordination spheres. In solid state, there are π⋯π, C–H⋯F, C–H⋯O, and F⋯F interactions between adjacent units to generate 3D supramolecular structure.
