Hydrothermal synthesis of nitrogen and boron doped carbon quantum dots with yellow-green emission for sensing Cr(<scp>vi</scp>), anti-counterfeiting and cell imaging

Abstract

Nitrogen and boron co-doped carbon quantum dots with great stability in high-salt conditions and good photostability are prepared through hydrothermal method and utilized for fluorometric detection of Cr(<sc>vi</sc>), anti-counterfeiting and cell imaging.
