Abstract
The vibrational spectra of the rare-earth pyrosilicates Lu2Si2O7 (C structure), Gd2Si2O7 (E structure), Gd2Si2O7:La (11 mol %) (A structure), and Gd2Si2O7:Ce (15 mol %) (F structure) have been studied by Raman spectroscopy. High-temperature Raman spectroscopy has been used to investigate the A → F phase transformation of Gd2Si2O7:La (11 mol %). Based on analysis of the Raman spectra, we discuss earlier proposed structures of the crystal lattices of the A-, C-, E-, and F-phases of the rare-earth pyrosilicates.
