摘要: 蓝光准二维钙钛矿发光二极管(PeLED)因具有优异的色纯度和可调发射特性而受到广泛关注，但其性能仍容易受相分布不均、能量传递受限及非辐射复合增强等因素的制约。甲氧基苯乙胺相较于苯乙胺具有不同的分子偶极特征，其引入能够影响准二维钙钛矿的结晶组装过程，调节不同n值相的形成比例与分布状态，并促进相间能量传递和激子辐射复合。本文围绕甲氧基苯乙胺在蓝光准二维钙钛矿中的作用展开讨论，分析其对薄膜发光质量及器件性能的影响。该策略为优化蓝光PeLED发光层结构和提升器件性能提供了新的思路。
Abstract: Blue quasi-two-dimensional perovskite light-emitting diodes (PeLEDs) have attracted widespread attention due to their excellent color purity and tunable emission properties; however, their performance remains limited by factors such as uneven phase distribution, restricted energy transfer, and enhanced non-radiative recombination. Compared to phenethylamine, methoxyphenethylamine possesses distinct molecular dipole characteristics. Its introduction can influence the crystallization and assembly process of quasi-two-dimensional perovskites, modulate the formation ratio and distribution of phases with different n-values, and promote inter-phase energy transfer and radiative exciton recombination. This paper discusses the role of methoxyphenethylamine in blue-light quasi-two-dimensional perovskites and analyzes its impact on the luminescence quality of thin films and device performance. This strategy provides a new approach for optimizing the structure of blue-light PeLED emitting layers and enhancing device performance.
