据美国能源部称，预计到 2030 年，用白光发光二极管 (WLED) 取代传统的白炽灯、卤素灯和荧光灯将使全球电力消耗减少三分之一。目前的 WLED 技术使用基于稀土元素 (REE) 的荧光粉材料，这不仅成本高昂，而且还构成环境问题。因此，研究人员正在寻找可以替代 WLED 中传统荧光粉的新一代光电材料，从而为未来打造更清洁、更节能的照明技术。发光金属有机框架 (LMOF) 最近作为 MOF 的一个新子类出现，在传感、成像、光电子学和固态照明 (SSL) 技术。LMOFs 可以通过金属中心、连接体和客体分子的合理设计和优化、易于制造成器件以及结构稳健性来实现高发光量子产率、可调谐激发和发射等优点，作为照明荧光粉的游戏规则改变者. LMOF 的这些明显的优势特性使其比其他当代材料更胜一筹，并使其成为用于 WLED 技术的未来荧光粉材料。在这篇专题文章中，我们将概述用于 SSL 的基于 LMOF 的荧光粉材料的最新发展，特别关注 WLED 技术。重点将集中在无 REE LMOF，

Luminescent MOFs (LMOFs): recent advancement towards a greener WLED technology

The replacement of traditional incandescent, halogen and fluorescent lamps by white light emitting diodes (WLEDs) is expected to reduce the global electricity consumption by one-third by 2030, according to the US Department of Energy. The current WLED technology uses rare-earth element (REE) based phosphor materials, which, not only is cost-intensive but also constitutes an environmental concern. Hence, researchers are in a quest for a new-generation of opto-electronic materials that can replace the conventional phosphors in WLEDs and thus aim towards a cleaner and more energy efficient lighting technology for the future. Luminescent metal–organic frameworks (LMOFs) have recently emerged as a new sub-class of MOFs which have demonstrated enormous potential for applications in sensing, imaging, optoelectronics and in solid-state lighting (SSL) technology. LMOFs could be game changers as lighting phosphors due to advantages such as high luminescence quantum yield, tunable excitation and emission which can be achieved by rational design and optimization of metal centers, linkers, and the guest molecules, facile fabrication into devices, and structural robustness. These clear advantageous features of LMOFs make them score over other contemporary materials, and enable them to be futuristic phosphor materials for WLED technology. In this feature article, we will provide an overview of the most recent developments of LMOF-based phosphor materials for SSL with a special focus on WLED technology. The emphasis will be centered around REE-free LMOFs, as the aim is to direct the attention of the readers towards a more viable and greener lighting technology.
