金属卤化物钙钛矿发光二极管具有颜色可调、色纯度高、光谱稳定性好等优点,成为近年来的研究热点。溶液加工的多晶薄膜钙钛矿发光二极管制备工艺简单且成本低,但结晶过程中容易形成缺陷,进而影响器件性能。本文提出采用低成本的葡萄糖作为钝化剂,制备多晶薄膜钙钛矿发光二极管,葡萄糖的加入有效抑制了器件中缺陷诱导非辐射复合损失。在葡萄糖浓度为0.2 mol·L

,光谱稳定性及色纯度好,且表现出较好的重复性。本文为多晶薄膜钙钛矿发光二极管中缺陷的钝化提供了简单而有效的方法。
Metal-halide perovskite light-emitting diodes have become a research hotspot in recent years, for they have the advantages of tunable emission color, high color purity and excellent spectral stability. Solution processed polycrystalline thin film perovskite light-emitting diodes have simple and low-cost preparation process, but it is easy to form defects in the crystallization process, which will affect the performance of the device. In this work, low-cost glucose is used as passivation agent to prepare polycrystalline thin film perovskite light-emitting diodes. The addition of glucose can effectively inhibit the trap-assisted nonradiative recombination loss in the devices. When the glucose concentration was 0.2 mol·L
-1
, the maximum brightness of the device reached 11 840 cd·m
-2
, the maximum current efficiency was 7.89 cd·A

. Our devices have excellent spectral stability, color purity and repeatability. This work provides a simple and effective method for the passivation of defects in polycrystalline thin film perovskite light-emitting diodes.
