The development of novel, efficient and cost-effective emitters for solid-state lighting devices (SSLDs) is ubiquitous to meet the increasingly demanding needs of advanced lighting technologies. In this context, the emergence of thermally activated delayed fluorescence (TADF) materials has stunned the photonics community. In particular, inorganic TADF material-based compounds can be engineered by chemical modification of the coordinated ligands and the type of metal centre, allowing control of their ultimate photo-/electroluminescence properties, while providing a viable emitter platform for enhancing the efficiency of state-of-the-art organic light-emitting diodes (OLEDs) and light-emitting electrochemical cells (LECs). By presenting an overview of the state of the art of all metal complex-based TADF compounds, this review aims to provide a comprehensive, authoritative and critical reference for their design, characterization and device application, highlighting the advantages and drawbacks for the chemical, photonic and optoelectronic communities involved in this interdisciplinary research field.
开发用于固态照明设备（SSLD）的新型、高效且经济高效的发光体对于满足先进照明技术日益增长的需求至关重要。在此背景下，热激活延迟荧光（TADF）材料的出现震惊了光子学界。特别是，基于无机TADF材料的化合物可以通过对配位配体和金属中心类型进行化学修饰来设计，从而控制其最终的光致/电致发光特性，同时为提高现有有机发光二极管（OLED）和发光电化学电池（LEC）的效率提供一个可行的发光体平台。通过概述所有基于金属配合物的TADF化合物的现状，本综述旨在为其设计、表征和器件应用提供全面、权威且批判性的参考，突出参与这一跨学科研究领域的化学、光子学和光电子学界的优势与不足。
