Luminescent materials have found a wide variety of applications, including information displays, lighting, X-ray intensification and scintillation, and so on. Therefore, much effort has been devoted to exploring novel luminescent materials so far. In the past decade, defect-related luminescent materials have inspired intensive research efforts in their own right. This kind of luminescent material can be basically classified into silica-based materials, phosphate systems, metal oxides, BCNO phosphors, and carbon-based materials. These materials combine several favourable attributes of traditional commercially available phosphors, which are stable, efficient, and less toxic, being free of the burdens of intrinsic toxicity or elemental scarcity and the need for stringent, intricate, tedious, costly, or inefficient preparation steps. Defect-related luminescent materials can be produced inexpensively and on a large scale by many approaches, such as sol-gel process, hydro(solvo)thermal reaction, hydrolysis methods, and electrochemical methods. This review article highlights the recent advances in the chemical synthesis and luminescent properties of the defect-related materials, together with their control and tuning, and emission mechanisms (solid state physics). We also speculate on their future and discuss potential developments for their applications in lighting and biomedical fields.
发光材料已经有了广泛的应用，包括信息显示、照明、X 射线增强和闪烁等。因此，迄今为止，人们一直在努力探索新型发光材料。在过去的十年中，缺陷相关的发光材料激发了人们的研究兴趣。这种发光材料可以基本分为硅基材料、磷酸盐体系、金属氧化物、BCNO 荧光粉和碳基材料。这些材料结合了传统商业可用荧光粉的几个有利特性，即稳定、高效且毒性较小，没有固有毒性或元素稀缺性的负担，也不需要严格、复杂、繁琐、昂贵或低效的制备步骤。缺陷相关的发光材料可以通过多种方法，如溶胶-凝胶法、水（溶剂）热反应、水解方法和电化学方法来廉价且大规模地制备。本文综述了缺陷相关材料的化学合成和发光性能的最新进展，以及它们的控制和调谐、发射机制（固态物理）。我们还对它们的未来进行了推测，并讨论了它们在照明和生物医学领域的应用的潜在发展。
