Optical properties and electronic structure of Pr3+ ion in KLa0.75Pr0.25(MoO4)2 have been investigated. The standard spectroscopy (excitation and photoluminescence spectra) and the high pressure spectroscopy methods have been used. Hydrostatic pressure up to 100 kbar has been applied in diamond anvil cell. The luminescence related to the transitions from the 3P0 and 1D2 states have been measured at ambient temperature for different pressures. We have found that the pressure shifts of the observed emission lines are negative and equal to 2–3 cm–1/kbar. It is due to the changes in Slater and α, β, γ parameters and diminishing of the spin-orbit coupling constant ζ.
