摘要/Abstract

碳点不仅具有类似于传统量子点的强发光和小尺寸特性，还表现出传统量子点无法比拟的水相分散性和生物相容性等优势.作为量子点领域的一个新兴分支，碳点的结构、合成化学和光电性质与传统量子点显著不同，也为量子点的发展提供了新的机遇和挑战.随着碳点领域的迅速发展和不断深化，越来越有必要在一些基本概念上与传统量子点比较，并从传统量子点的角度澄清碳点的独特特征和关键挑战.本综述主要聚焦于基本结构、合成化学、光学性质和应用研究等四个方面，从传统量子点基础概念的角度来重新审视碳点领域的研究进展和挑战.

Carbon dots (CDots) not only possess the characteristics of strong luminescence and small size similar to traditional quantum dots, but also show the advantages of good water dispersibility and biocompatibility beyond traditional quantum dots. As an emerging branch of the quantum dots family, the structure, synthetic chemistry and photoelectric properties of CDots are quite different from those of traditional quantum dots, which also provide new opportunities and challenges for the development of quantum dots. With the rapid development and deepening of the field of CDots, it is more and more necessary to compare them with traditional quantum dots on some basic concepts, and to clarify the unique characteristics and key challenges of CDots from the view of traditional quantum dots. In this review, we focus on the aspects of basic structure, synthetic chemistry, optical properties and application research, in an effort to reexamine the research progress and challenges in CDots from the view of fundamental concepts of traditional quantum dots.
Key words: carbon dots, traditional quantum dots, optical property, biological application, photoelectronic devices, catalysis
