Aqueous Afterglow Dispersion Enabling On‐Site Ratiometric Sensing of Mercury Ions (Advanced Optical Materials 34/2024)

Aqueous Afterglow Dispersion Enabling Mercury Ion Sensing This cover image illustrates the application of an aqueous-phase phosphorescent probe for the detection of heavy metal ions. The carbon dots (CDs)@hydrogen-bonded organic frameworks (HOFs) composite material functions as the energy donor, while a rhodamine B derivative acts as metal ions probe and the energy acceptor, facilitating the phosphorescent detection of mercury ions in aqueous environments via a Förster energy transfer mechanism. This approach highlights the potential of aqueous phosphorescent materials for environmental monitoring and analytical applications.
