虽然Mn掺杂的卤化铅钙钛矿可以减轻Pb的环境负担，但它们的合成过程受到复杂操作、高操作温度、低产量或有毒强极性溶剂的影响。对于钙钛矿衍生的应用而言，开发用于Mn掺杂的卤化物钙钛矿的简单且绿色的路线并进行大规模生产是高度期望的。在这项工作中，我们开发了一种简便和环境友好的合成策略，用于大规模制备Mn掺杂的卤化铅钙钛矿纳米晶体。纳米晶体是通过机械合成过程中没有有机溶剂。我们研究了原子组成对其形貌、晶体结构和光学性能的影响。结果表明，钙钛矿纳米晶具有Mn ~（2+）的4 T1 → 6A 1跃迁和钙钛矿基质的激子复合的双重发射。所获得的Mn：CsPbX 3纳米晶体在用作LED荧光粉时表现出良好的显色性。这项工作为Mn掺杂的钙钛矿生产提供了一种可扩展且简便的策略，而无需有机溶剂，这有望实现低成本和环保的LED。
Although Mn-doped lead halide perovskites could alleviate the environmental burden of Pb, their synthesis process suffers from intricate operations, high operating temperature, low production, or toxic strong polar solvents. Developing a simple and green route for Mn-doped halide perovskites with mass production is highly desirable for perovskite-derived applications. In this work, we developed a facile and environmental-benign synthesis strategy for large-scale preparation of Mn-doped lead halide perovskite nanocrystals. The nanocrystals were prepared via a mechano-synthesis process without organic solvents. We investigated the influence of atomic composition on their morphology, crystal structure and optical performance. Our results show that the perovskite nanocrystals have dual-emissions from the4T1to6A1transition of Mn2+and the excitonic recombination of perovskite hosts, respectively. The achieved Mn:CsPbX3nanocrystals show well-tailored color rendering when used as LED phosphors. This work presents a scalable and facile strategy for Mn-doped perovskite production without organic solvents, which promises low-cost and eco-friendly LEDs.
