Luminescent hydrogels are emerging soft materials with applications in photoelectric, biomedicine, sensors and actuators, which are fabricated via covalently conjugation of luminophors to hydrogelators or physical loading of luminescent organic/inorganic materials into hydrogel matrices. Due to the intrinsic stimulus-responsiveness for hydrogels such as thermo-, pH, ionic strength, light and redox, luminescent hydrogels could respond to external physical or chemical stimuli through varying the luminescent properties such as colors, fluorescent intensity and so on, affording diverse application potential in addition to the pristine individual hydrogels or luminescent materials. Based on the rapid development of such area, here we systematically summarize and discuss the design protocols, properties as well as the applications of stimulus-responsive luminescent hydrogels. Because of the stimuli-responsiveness, biocompatibility, injectable and controllability of luminescent hydrogels, they are widely used as functional smart materials. We illustrate the applications of luminescent hydrogels. The future developments about luminescent hydrogels are also presented.
发光水凝胶是一类新兴的软物质材料，在光电、生物医药、传感器和驱动器等领域有广泛的应用。这些水凝胶可以通过将发光体共价键接到水凝胶形成剂上，或者将有机/无机发光材料物理负载到水凝胶基质中进行制备。由于水凝胶具有内在的刺激响应性，如热、pH 值、离子强度、光和氧化还原等，发光水凝胶可以通过改变发光性质（如颜色、荧光强度等）对外界物理或化学刺激做出响应，从而除了原始的水凝胶或发光材料之外，还具有更多的应用潜力。基于该领域的快速发展，我们系统地总结和讨论了刺激响应发光水凝胶的设计方案、性能以及应用。由于发光水凝胶具有刺激响应性、生物相容性、可注射性和可控性，因此被广泛用作功能智能材料。我们说明了发光水凝胶的应用。还提出了关于发光水凝胶的未来发展。
