Over the past few decades, the sphere of applied science has witnessed soaring demand in developing high performance, novel and sustainable materials due to ever-increasing population coupled with need for alternative-green-energy resources. Inevitably, sulfur research expands through the breadth of materials sciences including sustainable use of the by-products obtained from petroleum industry, preparation of biocompatible materials, and constructing energy harvesting devices, indispensable to our everyday lives. Congruous with popular heavy-metal free elemental quantum dots such as the carbon, silicon and phosphorus, emergence of sulfur quantum dots (SQDs) has drawn substantial attention due to their bright luminescence, infrequent to other sulfur allotropes. In this review article, we focus some of the pioneering advances on synthesis and characterizations of luminescent sulfur nanodots and their potential applications in bioimaging, fabrication of light emitting devices, sensing and catalysis. Finally, critical challenges along with future perspectives corresponding to this newly discovered research area have been discussed.
在过去的几十年中，由于人口的不断增加以及对替代绿色能源资源的需求，应用科学领域对高性能、新型和可持续材料的需求急剧上升。不可避免的是，硫的研究通过包括可持续利用石油工业副产品、制备生物相容性材料以及构建对我们日常生活不可或缺的能量收集装置等材料科学的广度不断扩展。与流行的无重金属元素量子点（如碳、硅和磷）一样，硫量子点 (SQD) 的出现引起了人们的极大关注，因为它们具有明亮的荧光，而其他硫同素异形体则很少见。在这篇综述文章中，我们重点介绍了一些关于发光硫纳米点的合成和特性方面的开创性进展，以及它们在生物成像、发光器件制造、传感和催化等方面的潜在应用。最后，讨论了对应这个新发现的研究领域的关键挑战和未来展望。
