具有优异光学性能的纳米晶材料引起了人们极大的兴趣，被认为是新一代光电器件的候选材料。在过去的几年中，已经做出了许多努力来克服PeNCs和相关设备和系统的可持续制造方面的挑战，包括用于前体制备的溶剂，用于制造设备和系统的反溶剂和钙钛矿材料，并且已经取得了显着的进展。然而，在PeNCs的合成中使用有毒的有机溶剂对生态系统和人类健康构成了威胁，这阻碍了PeNCs的商业化和产业化的进展。这促进了绿色溶剂的开发，以可持续地制造PeNCs。在这篇专题文章中，介绍了一种用于合成PeNCs的最先进的绿色方法，其中强调了低毒性的溶剂，与报道的综述相反，这些综述侧重于制备前体溶液的毒性溶剂。然后，我们集中在绿色，水的方法制备的PeNCs，包括传统的钙钛矿和双PeNCs，通过总结我们以前的研究工作和研究。特别地，纯水作为最绿色的溶剂被引入用于制备PeNCs，并且讨论了影响PeNCs的尺寸和光学特性的参数，例如超声处理时间和用于后处理的配体。综述了利用钝化层提高PeNCs水稳定性的策略，PeNCs分为有机聚合物和无机半导体。我们强调的挑战和可能的解决方案，在绿色制造和应用的PeNCs。本文中讨论的PeNCs合成的绿色路线有望成为PeNCs制造的商业化和工业化的重要一步。预计绿色制造将继续成为PeNCs合成和制造的主流。
Perovskite nanocrystals (PeNCs) with excellent optical properties have attracted tremendous research interests and have been considered as promising candidates for new-generation optoelectronic devices. Over the past few years, numerous efforts have been made to overcome the challenges in terms of sustainable manufacturing of PeNCs and related devices and systems, including the solvents used in precursor preparation, antisolvents and perovskite materials for the fabrication of devices and systems, and remarkable progress has been made. However, the usage of toxic, organic solvents in the synthesis of PeNCs poses a threat to the ecosystem and human health, which has hindered the progress in the commercialization and industrialization of PeNCs. This has promoted the development of green solvents for the sustainable manufacturing of PeNCs. In this Feature Article, a state-of-the-art green method for the synthesis of PeNCs is presented, in which the solvents of low toxicities are underlined in contrast to the reported Reviews which focus on toxic solvents for the preparation of precursor solutions. We then focus on green, aqueous methods for the preparation of PeNCs, including conventional perovskite and double PeNCs, by summarizing our previous research efforts and studies. In particular, pure water as the greenest solvent is introduced for the preparation of PeNCs, and the parameters affecting the size and optical characteristics of PeNCs, such as sonication time and ligands for post-treatment, are discussed. The strategies of using a passivation layer to improve the aqueous stability of PeNCs are reviewed, which are grouped into organic polymers and inorganic semiconductors. We highlight the challenges and possible solutions in the green manufacturing and applications of PeNCs. The green routes discussed in this article for the synthesis of PeNCs are expected to be a major step forward for the commercialization and industrialization of the fabrication of PeNCs. It is anticipated that green manufacturing will continue to be the mainstream in the synthesis and fabrication of PeNCs.
