Abstract

A facile one-step and green synthesis method was developed to prepare water soluble, environmentally friendly, and highly nitrogen-doped carbon quantum dots (CQDs) with tunable properties. As a proof-of-concept application, a multifunctional electronic device with the configuration of PEDOT:PSS/s-CQD@SWCNT/PEDOT:PSS was fabricated through a full-solution process, which exhibits memory and current limiting behavior, with the merit of stable operation and reliable endurance.
