Abstract: Detailed spectroscopic studies of Pr3+ ions in BiBO glass and Ca4GdO(BO3)3 crystal were performed.Experimental absorption spectra were measured at room temperature and assigned.The first principles discrete variational multielectron method was used to model the polarized absorption spectra of the Ca4GdO(BO3)3:Pr3+;without any fitting parameters,the overall appearance of the spectra was reproduced satisfactorily.The energy intervals between different molecular orbitals in the [PrO6]cluster were estimated.The conventional Judd-Ofelt theory was used to calculate the oscillator strengths of the 4f-4f transitions in the BiBO:Pr3+ system;the set of the phenomenological intensity parameters was determined.
