The current challenges of pH-sensitive C-dots and their future research focus are also proposed here. In this review, we systematically summarize the pH-sensitive PL properties and the pH-sensitive PL mechanism, as well as recent research progress of C-dots in pH sensing. Of note, C-dots show intrinsic pH-sensitive photoluminescence (PL), indicating their great potential for pH sensing, especially in biotic pH sensing. C-dots exhibit good optical properties, such as tunable emission wavelength, good photostability, nonblinking, up-conversion emission, etc. With these merits, C-dots have been used in a wide range of applications including sensing, bioimaging, catalysis, and light-emitting devices. C-dots have attracted immense attention because of their unique optical properties, excellent biocompatibility, facile preparation, and low cost. 2Hubei Key Laboratory of Environmental and Health Effects of Persistent Toxic Substances, Institute of Environment and Health, Jianghan University, Wuhan, ChinaĬarbon nanodots (C-dots) with sp 2/sp 3 framework and diameter of 1Department of Biophysics, School of Basic Medical Sciences, Institute of Medical Engineering, Xi'an Jiaotong University Health Science Center, Xi'an, China.Cui Liu 1 *, Fang Zhang 1, Jiao Hu 2, Wenhui Gao 1 and Mingzhen Zhang 1
