Abstract: The study of the f  d transition on Ce3+-doped Cs2NaLuCl6, through the absorption and emission spectra at high pressure, allows us to conclude that the equilibrium Ce–Cl bond distance in the excited state is shorter than in the ground state. The observed band shifts of –530 ± 20 cm–1/GPa and –415 ± 10 cm–1/GPa in absorption and emission, respectively, reveal reduction of the Stokes shift and the spin–orbit interaction with pressure.
