Carbon Dots with Up-Conversion Luminescence as pH Nanosensor

Carbon Dots with Up-Conversion Luminescence as pH Nanosensor

In this study, the up-conversion luminescence for aqueous suspensions of carbon dots with polyfunctional and carboxylated surfaces synthesized by a hydrothermal method was investigated. The obtained quadratic dependence of the luminescence intensity on the power of the exciting radiation indicates t...
