论文摘要
采用一种易于的，低温降水的方法来证明合成超薄和高度均匀的邻氨基溴化溴化物钙钛矿纳米线（NWS）的合成。这些反应促进了NWS的结晶性质，而微米大小的长度则赋予量身定制的纳米线宽度，范围从量子限制状态（〜7 nm）到2.6 nm。这种胶体合成方法是在工作台上进行的第一种胶体合成方法，而无需化学合成设备。重要的是，随着时间的流逝，NWS光致发光已得到改善，没有繁琐的结合后表面处理要求。
A facile, low-temperature precipitation-based method is utilized to demonstrate 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) and 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 become improved over time, with no tedious post-synthesis surface treatment requirement.
