　　In this paper, we investigate the Raman and photoluminescence spectra of Y₂O₃/Eu³⁺ and Y₂O₃/Eu³⁺/Mg²⁺ nanorods under high pressures using 514-nm and 532-nm laser light excitation. We observe transitions from the initial cubic phase to amorphous at pressures higher than 24 GPa for both Y₂O₃/Eu³⁺ and Y₂O₃/Eu³⁺/Mg²⁺ nanorods. In addition, Y_2<...
