Colloidal perovskite nanocrystals (PNCs) combine the outstanding optoelectronic properties of bulk perovskites with strong quantum confinement effects at the nanoscale. Their facile and low-cost synthesis, together with superior photoluminescence quantum yields and exceptional optical versatility, make PNCs promising candidates for next-generation optoelectronics. However, this field is still in its early infancy and not yet ready for commercialization due to several open challenges to be addressed, such as toxicity and stability. Here, the key synthesis strategies and the tunable optical properties of PNCs are discussed. The photophysical underpinnings of PNCs, in correlation with recent developments of PNC-based optoelectronic devices, are especially highlighted. The final goal is to outline a theoretical scaffold for the design of high-performance devices that can at the same time address the commercialization challenges of PNC-based technology.
胶体钙钛矿纳米晶体（PNCs）将块状钙钛矿出色的光电特性与纳米尺度上强大的量子限制效应结合在一起。它们简便且低成本的合成方法，以及卓越的光致发光量子产率和出色的光学多功能性，使PNCs成为下一代光电器件的有前景的候选材料。然而，由于存在诸如毒性和稳定性等若干有待解决的公开挑战，该领域仍处于起步阶段，尚未准备好商业化。在此，将讨论PNCs的关键合成策略和可调谐光学特性。特别强调了PNCs的光物理基础，以及与基于PNCs的光电器件的最新进展的相关性。最终目标是勾勒出一个用于设计高性能器件的理论框架，该框架能够同时应对基于PNCs技术的商业化挑战。
