Color-changing materials have a variety of applications, ranging from smart windows to sensors. Here, we report deliquescent chromism of thin, color neutral films of nickel(II) iodide (NiI2) that are less than 10 μm thick. This behavior does not occur in the bulk material. Dark brown thin films of crystalline NiI2 turn clear when exposed to humidity and can be switched back to the dark state when mildly heated (>35 °C). This optical transition between dark and clear states of an NiI2 thin film is reversible with thermal cycling.

碘化镍（II）薄膜的潮红色度
变色材料具有多种应用，从智能窗户到传感器。在这里，我们报道了厚度小于10μm的碘化镍（III 2）薄膜，彩色中性膜的潮解性色变。在散装物料中不会发生此行为。暴露于湿气中，呈结晶状的NiI 2的深棕色薄膜会变透明，而在温和加热（> 35°C）时可以切换回黑暗状态。NiI 2薄膜在暗态和透明态之间的这种光学转变可通过热循环来逆转。
