Solid-state materials with tunable light emission characteristics offer an attractive prospect. Unique luminescence features of trivalent lanthanide (Ln^III) ions—sharp characteristic emission in the visible and near-infrared (NIR) spectral regions, exceptional color purity, long luminescence lifetimes, high quantum yield and large Stokes shifts—afford them as promising white-light source materials. The review provides an overview of the recent developments in the Ln- complex-based solid-state white-light emitters with particular emphasis on different design strategies and photoluminescence features to augment the foundations of factual knowledge further. The approaches adopted in the lanthanide coordination complexes—logical codoping of Ln^III in various compositions, lanthanide encapsulation in MOF pores, infinite coordination particles, and lanthanide incorporated composites—to attain tunable white-light emission, will be discussed. The pros and cons of different adopted strategies in term of further processing of the materials into real-world applications as well as the imminent challenges are also reviewed and put in prospect.

具有可调光发射特性的固态材料提供了诱人的前景。三价镧系离子（Ln ^III）的独特发光特性-在可见和近红外（NIR）光谱区域内具有鲜明的特征发射，出色的色纯度，长的发光寿命，高量子产率和大的斯托克斯位移-使其被誉为有前途的白光-光源材料。这篇综述概述了基于Ln配合物的固态白光发射器的最新发展，特别强调了不同的设计策略和光致发光特性，以进一步增强事实知识的基础。镧系元素配合物所采用的方法— Ln ^III的逻辑共掺杂在各种组成中，将讨论镧系元素在MOF孔中的包封，无限配位颗粒和掺入镧系元素的复合材料-以获得可调的白光发射。本文还回顾并展望了在将材料进一步加工到实际应用中方面所采用的不同策略的优缺点以及迫在眉睫的挑战。
