A luminescent Terbium-Succinate MOF thin film fabricated by electrodeposition for sensing of Cu2+ in aqueous environment

- A Tb-MOF luminescent thin film sensor for detecting Cu(II) ion in aqueous media was developed.
- The films were one-step fabricated via electrodeposition under mild condition.
- The films can detect 0.1 mM Cu(II) in water within 10 min via naked-eyes.
