摘　　要：圆偏振发光(CPL)是手性材料受到激发后发射出具有差异的左旋或右旋圆偏振光的独特光学现象,可以应用于量子计算、信息加密和三维显示等领域.随着纳米科学和技术的发展,具有CPL性能的手性稀土纳米材料因其出色的光学稳定性等特点而备受关注,并具有大的应用潜力.本文综述了手性稀土纳米材料的最新研究进展,首先介绍了稀土元素的光谱特性及早期手性稀土配合物的研究,详述了如何构筑具有CPL的手性稀土纳米材料,强调了合成过程中手性结构对发光性能的调控特点,并通过主-客体策略讨论了如何通过稀土发光客体与手性主体的选择来优化CPL性能.最后,探讨了CPL稀土纳米材料领域面临的挑战,如发光性能和手性控制等问题,并对手性稀土纳米材料在未来的应用前景进行了展望.Circularly polarized luminescence(CPL) represents a distinctive optical phenomenon where chiral materials emit either left-handed or right-handed circularly polarized light upon excitation. This property finds applications in fields such as quantum computing, information encryption, and three-dimensional displays. As advancements in nanoscience and technology, chiral rare earth nanomaterials exhibiting CPL properties have garnered considerable attention for their exceptional optical stability and substantial potential for practical applications. This review comprehensively discusses the latest advances in chiral rare earth nanomaterials. It begins with an overview of the spectral characteristics of rare earth elements and the early research on chiral rare earth complexes. The review then details the construction methods for chiral rare earth nanomaterials with CPL properties, highlighting the role of chiral structures in modulating CPL properties during synthesis. Utilizing host-guest strategies, this review also summarizes how the selection of rare earth luminescent guests and chiral hosts can enhance CPL properties. Finally, it discusses the challenges within the field of rare earth nanomaterials with CPL and looks forward to future applications of these materials in various technological areas.
