Kopsavilkums

Theoretical analysis of optical properties of two recently synthesized phosphors with the Ce³⁺ ions (Na₃LuSi₂O ₇ and NaSr₄(BO₃)₃) was performed. The exchange charge model of crystal field was used to calculate the crystal field parameters and cerium 5d states splittings for each site in Na ₃LuSi₂O₇. Analysis of vibronic coupling of Ce³⁺ in NaSr₄(BO₃)₃ resulted in a quantitative modeling and theoretical simulation of the experimental spectra. Electronic energy levels, vibrational frequencies and ion-lattice vibronic coupling strength are determined specifically for Ce³⁺ at different sites. The performed analysis allows for getting detailed description of the optical properties of trivalent cerium in the considered crystals and provides a general guide to understanding and characterizing other Ce³⁺ activated phosphors.
