Zero-dimensional lead halide perovskite nanocrystals (NCs) exhibit size-dependent bandgap and carrier confinement compared to bulk counterparts due to the quantum confinement effect, making them essential for achieving wide-color-gamut displays, studying excitonic spin relaxation, and constructing superlattices. Despite their promising potential, they face a variety of technical bottlenecks, such as insufficient color reproducibility, limited large-scale production, low stability, and toxicity. An outline of a research roadmap is provided in the review, which highlights key challenges in developing perovskite NCs for commercial applications.
由于量子限制效应，零维卤化铅钙钛矿纳米晶体（NCs）与块状材料相比，表现出尺寸依赖的带隙和载流子限制，这使得它们对于实现广色域显示、研究激子自旋弛豫以及构建超晶格至关重要。尽管它们具有广阔的潜力，但它们面临着各种技术瓶颈，如颜色再现性不足、大规模生产受限、稳定性低和毒性等。该综述提供了一个研究路线图大纲，突出了开发用于商业应用的钙钛矿纳米晶体的关键挑战。
