The widely used one‐step spin‐coating method for perovskites suffers due to the narrow processing window of antisolvents. In article number 1901162, Shuyu Zhang and co‐workers demonstrate a solution; incorporating Nd3⁺ into MAPbBr3 perovskites. The Nd3⁺ incorporation leads to a significantly broadened processing window for antisolvent dripping. The films exhibit high stability with enhanced PLQY and phase purity due to induced heterogeneous nucleation.

钙钛矿：三价钕调制的MAPbBr3钙钛矿的成核和生长：一步法制备高效发光钙钛矿的超宽加工窗口（Adv。Electron。Mater。3/2020）

由于抗溶剂的加工窗口狭窄，因此钙钛矿广泛使用的一步旋涂法受到了困扰。在书号1901162中，张书宇及其同事演示了一种解决方案。将Nd3 ⁺掺入MAPbBr3钙钛矿中。Nd3 ^+的掺入会大大增加抗溶剂滴落的处理范围。由于诱导的异相成核，该膜表现出高稳定性和增强的PLQY和相纯度。
