The possibilities of the use of Eu3+ in extracting information of the pressure effects on the nature of itscrystal site in the NH4·Eu(SO4)2 catalytic host are closely inspected through the study of emission spectra forapplied pressures up to 87 kbar. The phenomenological crystal field analysis of these spectra reveals cleardiscontinuities, at ~30 kbar, the sharper ones, and then at ~70 kbar, in crystal field strength trends, whichtaken together with structure-based simulations of crystal field interactions indicate well-defined pressure-induced anisotropic distortions in Eu3+ local environments.
