Perovskites: Trivalent‐Neodymium Additive Modulated MAPbBr3 Perovskite Nucleation and Growth: Ultrawide Processing Window for One‐Step Fabrication of Efficient Light‐Emitting Perovskites (Adv. Electron. Mater. 3/2020)

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.
