“…3 have been measured in symmetric 90°scattering geometry. 38 The advantage of this scattering geometry is that it allows sound velocities to be measured without knowing the refractive index of the sample. 38 Velocities were hence directly determined from the Brillouin shifts B from the relation V = 90 / 2 sin 45, where is the wavelength of the laser light.…”

The authors report the results of temperature-dependent Brillouin scattering from both transverse and longitudinal acoustic waves, heat capacity studies as well as room temperature Raman scattering studies on M 2 O-MgO-WO 3 -P 2 O 5 glasses ͑M=K,Rb͒. These results were used to obtain information about structure and various properties of the studied glasses such as fragility, elastic moduli, ratio of photoelastic constants, and elastic anharmonicity. They have found that both glasses have similar properties but replacement of K + ions by Rb + ions in the glass network leads to decrease of elastic parameters and P 44 photoelastic constant due to increase of fragility. Based on Brillouin spectroscopy they show that a linear correlation between longitudinal and shear elastic moduli holds over a large temperature range. This result supports the literature data that the Cauchy-type relation represents a general rule for amorphous solids. An analysis of the Boson peak revealed that the form of the frequency distribution of the excess density of states is in agreement with the Euclidean random matrix theory. The reason of the observed shift of the maximum frequency of the Boson peak when K + ions are substituted for Rb + ions is also briefly discussed.

“…The cell is compact ͑about 5 cm in the maximum dimension͒, and easily fits onto any standard three-or four-circle goniometer, allowing a number of additional applications such as x-ray scattering, etc. Our Brillouin cell utilizes a symmetric scattering geometry 11 which yields velocity measurements independent of the refractive index. This is important because the refractive index can change appreciably with temperature.…”

A compact ceramic high-temperature cell for Brillouin spectroscopy was designed and tested. The cell can be mounted onto a three-or four-circle goniometer and allows collection of the full set of elastic constants of minerals to temperatures in excess of 1500 K from samples with dimensions of 100ϫ100ϫ20 m or smaller. As a test of the instrument the single-crystal elastic constants of MgO were measured to 1510͑10͒ K, and are found to be in excellent agreement with earlier independent results. The high-temperature cell should be useful for other types of spectroscopic measurements, and is especially useful in situations where spectral properties vary with the scattering geometry.
