We have facilely synthesized orange emissive carbon nanodots (O-CDs) via a hydrothermal method using citric acid and 5-aminosalicylic acid. The obtained O-CDs show the excellent characteristics of excitation independence, low toxicity, fabulous photostability and superior biocompatibility. Based on...
