Description

Single crystals of the Li3Na3In2F12 fluoride garnet have been studied by Fourier-transform infrared spectroscopy and Raman scattering. Polarized Raman spectra were recorded at low temperatures showing that the room-temperature phase is stable down to 7 K. Selected scattering geometries allow us to identify the Raman-active phonons based on the factor group analysis. The infrared reflectance spectrum was measured at room temperature and analysed on the basis of the four-parameter semi-quantum model. (author)
