Construction of nitrogen-doped carbon dots-europium ion coordination fluorescence sensing system for detection of pyridine-2,3-dicarboxylic acid
This study synthesized nitrogen-doped carbon dots (CDs) via microwave heating method and constructed a fluorescence sensing system based on europium ion (Eu3+) coordination for efficient detection of pyridine-2,3-dicarboxylic acid (DPA). The experiment systematically investigated the effects of Eu3+ concentration and s...
