Cesium lead halide perovskite nanocrystals (NCs) with excellent intrinsic properties have been employed universally in optoelectronic applications but undergo hydrolysis even when exposed to atmospheric moisture. In the present study, composite CsPbX (X = Cl, Br, and I) perovskite NCs were encapsulated with stretchable (poly(styrene-butadiene-styrene); SBS) fibers by electrospinning to prepare water-resistant hybrid membranes as multicolor optical active layers. Brightly luminescent and color-tunable hydrophobic fiber membranes (FMs) with perovskite NCs were maintained for longer than 1 h in water. A unique remote FMs packaging approach was used in high-brightness perovskite light-emitting diodes (PeLEDs) for the first time.
铯铅卤钙钛矿纳米晶体（NCs）具有优异的固有特性，已广泛应用于光电应用中，但即使暴露在大气湿度下也会发生水解。在本研究中，通过静电纺丝将复合 CsPbX（X = Cl、Br 和 I）钙钛矿 NCs 封装在可拉伸的（苯乙烯-丁二烯-苯乙烯；SBS）纤维中，以制备耐水混合膜作为多色光学活性层。具有钙钛矿 NCs 的高亮度发光且可调节颜色的疏水性纤维膜（FMs）在水中保持 1 小时以上。首次在高亮度钙钛矿发光二极管（PeLEDs）中使用了独特的远程 FMs 封装方法。
