a The crystal structure of Cd(BDC)(DMF) (H atoms are omitted for clarity) at ambient conditions. b 2D mapping of pressure-dependent PL intensity and wavelength of Cd(BDC)(DMF) (a.u. arbitrary units). PL spectra and corresponding PL photographs of Cd(BDC)(DMF) at 1 atm and after releasing pressure from c 18.3, d 26.1, and e 30.0 GPa. f Chromaticity coordinates of the PL for engineered Cd(BDC)(DMF) after releasing pressure from 18.3, 26.1, and 30.0 GPa. g Normalized prompt and delayed to 2 ms PL spectra, h PL decay curves of Cd(BDC)(DMF) after 18.0 GPa pressure treatment by the Walker-Type Large-Volume Press.
