Abstract Lanthanide metal‐organic frameworks (Ln‐MOFs) exhibit distinctive emission spectra and prolonged luminescent lifetimes, thereby offering a unique platform for the advancement of solid‐state photoluminescence (PL) materials. However, mismatch between energy levels metal ions organic ligands leads to weak PL emission. Herein, this study presents pressure‐treated strategy aimed at achieving efficient green in Tb 2 (BDC) 3 (H O) 4 MOF. Compared initial intensity, intensity is enhanced eightfold below 3.1 GPa. Intriguingly, sample amplified by 2.5‐fold compared state, monochromaticity maintained. Experiments calculations reveal that hydrogen bonds are retained ambient conditions after pressure treatment. They lock conjugated configuration formed planes carboxyl group benzene ring, facilitating intersystem crossing. The reduced distances drive ligand‐to‐metal transfer process. This finding provided significant insights into structure–property relationship , new boosting enhancement Ln‐MOFs.
