摘　　要：无机发光材料发光模式的高度集成为其多功能化应用以及多学科领域交叉发展提供了机遇。以能量陷阱为媒介的多模式发光主要基于陷阱捕获和释放载流子的过程。陷阱中的载流子可以在热、光或者力的刺激下从陷阱中逃逸,复合后产生热释光、光激励发光或力致发光等,从而使材料表现出优异的光物理特性。多模式无机发光材料在安全防伪、光信息存储、人机交互、生物医学等诸多领域展现出了应用潜力。从多模式发光机理切入,总结了陷阱的填充和排空机制,梳理了依赖于能量陷阱的多模式无机发光材料的发光机理和研究进展,展望了多模式发光材料的研究前景。The highly integrated luminescence modes of inorganic luminescent materials provide opportunities for their multi-functional applications and interdisciplinary development. The multimodal luminescence mediated by energy traps is mainly based on the processes of carrier trapping and releasing. The carriers in a trap can escape from this trap under the stimulation of heat, light, or force, and subsequently recombine to produce thermos-luminescence, photostimulated luminescence, or mechano-luminescence. The multimodal luminescent materials with excellent photophysical properties show potential applications in anti-counterfeiting, optical data storage, human-computer interaction, biomedicine, and so on. Herein, we reviewed the mechanism of multimodal luminescence, summarized the mechanism of trap filling and emptying, sorted out the research progress of energy-trap-dependent multimodal inorganic luminescent materials, and prospected the development trend of multimodal luminescent materials.
