The characteristics of N-CDs suitable for their optical applications or for use as nanozymes were demonstrated by rationalizing the relationship between the dopant content (e.g., the amount of doped N and types of chemical bonding) and physicochemical properties.

This article presents the Zn-assisted synthesis of N-doped carbon dots (N-CDs) with enhanced quantum yield (QY) and photostability. There have been intensive studies to improve or tune the optical properties...
