The construction of Tb3+ doped Sr–BDC metal–organic framework materials and their high-sensitivity fluorescent detection of Fe3+

Key Points

• The Tb3+-doped Sr–BDC MOF emits bright green light at 545 nm, enabling effective detection of Fe3+.
• The method showcased a limit of detection of 7.3 μM, ranging from 5 to 100 μM for Fe3+ ions.
• Synthesis was achieved using a solvothermal approach, optimizing the MOF's fluorescent properties.
• This technique may provide reliable monitoring for both environmental and biomedical applications.
