Data from: Nitrogen and chlorine co-doped carbon dots as probe for sensing and imaging in biological samples

Jin Li, Kai Tang, Jianxin Yu, Hanqin Wang, Mingli Tu & Xiaobo Wang
A facile one step hydrothermal synthesis approach was proposed to prepare nitrogen and chlorine co-doped carbon dots using l-ornithine hydrochloride as the sole precursor. The configuration and component of carbon dots were characterized by TEM, XPS, and FTIR. The obtained CDs (Orn-CDs) with a mean diameter of 2.1 nm were well monodispersed in aqueous solutions. The as-prepared CDs exhibited a bright blue fluorescence with a high yield of 60%, good photostability and low cytotoxicity. The...
