摘要

We present the high pressure photoluminescence study of Lu₂SiO₅:Ce³⁺ in the pressure range up to 32 kbar, with pressure applied in sapphire anvil cell supplied. We have observed the red pressure shift of the Ce³⁺ emission equal to −11.3 cm⁻¹/kbar for the 5d¹ → F_5/2 transition and −7.7 cm⁻¹/kbar for 5d¹ → F_7/2 transition related to increase of the crystal field splitting of the 5d¹ electronic configuration. We have found that local compressibility of Ce³⁺–ligands system of Lu₂SiO₅ is more than two times smaller than the bulk material compressibility.
