摘要：

All inorganic cesium lead halide perovskite semiconductors exhibit great potential for nanolasers, light-emitting diodes, and solar cells, because of their unique properties including low threshold, high quantum efficiency and low cost. However, the high material refractive index of perovskite semiconductors hinders light extraction efficiency for photonic and illumination applications. In this paper, we demonstrate high light extraction efficiency achieved in CsPbBr2.75I0.25 two-dimensional photonic crystals. The perovskite photonic crystals exhibit both emission rate inhibition and light energy redistribution simultaneously. We observed a 7.9-fold reduction of spontaneous emission rate with a slower decay in CsPbBr2.75I0.25 photonic crystals, because of the photonic bandgap effect (PBG). We also observed a 23.5-fold PL emission enhancement, as a result of light energy redistribution from 2D guided modes to vertical direction in perovskite photonic crystals thin films, indicating a high intrinsic light extraction efficiency. Such a combination of inhibiting undesirable emission with redistributing light energy into useful modes offers a new promising approach in various applications for perovskite, including solar cell, displays, and photovoltaics.
