In the last couple of years, carbon dots have emerged as a new novel luminescent particle for applications in fluorescence and microscopy in some ways analogous to quantum dots and silicon nanocrystals/particles. As with any fluorescent label or tag, absolute fluorescence intensity, brightness, and particle photostability are a primary concern. In this communication we subsequently show that similar to classical fluorophores, carbon dots located in the near-field, near to Plasmon supporting materials, show enhanced intensities and improved photostabilities.
在过去的几年中，碳点已成为一种新型的发光颗粒，在荧光和显微镜方面的应用与量子点和硅纳米晶体/颗粒有些类似。与任何荧光标记物或标签一样，绝对荧光强度、亮度和粒子光稳定性是首要关注的问题。在本通讯中，我们随后表明，类似于经典荧光团，位于近场、靠近支持等离子体的材料的碳点，显示出增强的强度和提高的光稳定性。
