Abstract

In this paper the pressure dependence of crystal field (CF) parameters and free-ion parameters of the Eu³⁺ ion in Y₂O₂S:Eu is studied experimentally in the pressure range from 0 to 13 GPa. Pressure strengthens the interionic interaction in the crystal. The CF strength parameter S increases by a factor of 11%. The Slater parameter F₂ and the spin-orbit parameter show about 0. 4 % and 0. 2 % decrease, respectively.
