Carbon dots (CDs) demonstrate unique luminescence properties due to conjugated π domains of the sp 2 / sp 3 hybridized carbon core, quantum-size effects, and passivation of CD surfaces by functional groups. In this work we present hydrothermal synthesis of nitrogen-doped and boron-doped CDs, their morphological, structural, optical characteristics, and luminescent properties. The CDs are first synthesized from trans- aconitic acid. X-ray photoelectron and infrared spectroscopy data indicate that prepared CDs contain nitrogen and boron atoms. The photoluminescence quantum yield of N-doped and B-doped CDs is 26% and 9%, respectively.

N 掺杂和 B 掺杂碳点的结构和光学特性

由于 sp 2 / sp 3 杂化碳核的共轭 π 域、量子尺寸效应和官能团对 CD 表面的钝化，碳点 (CD) 表现出独特的发光特性。在这项工作中，我们介绍了氮掺杂和硼掺杂 CD 的水热合成、它们的形态、结构、光学特性和发光特性。CDs 首先由反式乌头酸合成。X 射线光电子和红外光谱数据表明制备的 CD 含有氮和硼原子。N 掺杂和 B 掺杂 CD 的光致发光量子产率分别为 26% 和 9%。
