A facile, low-temperature precipitation-based method is utilized for the synthesis of ultra-thin and highly uniform cesium lead bromide perovskite nanowires (NWs). The reactions facilitate the NWs' crystalline nature over micron-size lengths, while they impart tailored nanowire widths that range from the quantum confinement regime (∼7 nm) down to 2.6 nm. This colloidal synthesis approach is the first of its kind that is carried out on the work-bench, without demanding chemical synthesis equipment. Importantly, the NWs' photoluminescence is shown to improve over time, with no requirement for tedious post-synthesis surface treatment.
一种简单、低温的沉淀法被用于合成超薄且高度均匀的卤化铯铅钙钛矿纳米线（NWs）。该反应促进了 NWs 在微米长度上的晶态特性，同时赋予了从量子限制（约 7nm）到 2.6nm 的定制纳米线宽度。这种胶体合成方法是同类中首次在工作台上进行的，而不要求使用化学合成设备。重要的是，NWs 的光致发光性能随着时间的推移而提高，不需要繁琐的后合成表面处理。
