1：Experimental Design and Method Selection:

The study involved synthesizing two series of Ln-MOFs using hydrothermal methods with specific organic linkers (H3L2 and H3BTB), followed by characterization using various techniques to analyze their structural, thermal, and luminescent properties. The rationale was to investigate the antenna effect and tune luminescence by varying lanthanide ions and linkers.

2：Sample Selection and Data Sources:

Samples were synthesized from lanthanide salts (La, Ce, Pr, Nd, Sm, Eu, Gd) and organic linkers purchased from commercial sources. Data were obtained from synthesized MOF powders.

3：List of Experimental Equipment and Materials:

Equipment included FT-IR spectrometer, PXRD diffractometer, TGA analyzer, SEM microscope, UV-Vis-NIR spectrophotometer, spectrofluorometers (Fluorolog 3-222 and FLS980), NMR spectrometer, and specific detectors and light sources. Materials included lanthanide salts, organic linkers, solvents (DMF, cyclohexanol, ethanol, DMSO-d6, CF3COOH, D2O).

4：Experimental Procedures and Operational Workflow:

Synthesis involved hydrothermal reaction at 85°C for 16h, followed by solvent exchange and drying. Characterization steps included PXRD, FT-IR, SEM, TGA, UV-Vis absorption, photoluminescence spectroscopy, quantum yield measurements, and lifetime decay measurements using TCSPC or MCS modes.

5：Data Analysis Methods:

Data were analyzed using fitting functions for decay curves (sum of exponentials), integration for quantum yield calculation, and comparison of spectral features and lifetimes.
