The structural relaxation dynamics in the glass-former B 2 O 3: a multi-speckle dynamic light scattering study

Autor: G. Pintori, Flavio Rossi, F. Riboli, Giulio Monaco, Maurizio Montagna, F. Dallari, B. H. Kintov, C. Armellini

Publikováno v: Philosophical Magazine. 96:800-808

A multi-speckle set-up for dynamic light scattering experiments has been implemented to investigate the relaxation dynamics in the glass-former at temperatures across the glass transition. When compared to literature data obtained with traditional si

Publikováno v: Journal of Non-Crystalline Solids. 352:4577-4582

The temperature dependence of the mean square displacement, 〈u2〉, calculated by elastic neutron scattering for two phosphate glasses, (AgI)x(AgPO3)1-x with x = 0.3, 0.55, is analysed. The studied samples are probed in a wide range of temperatures

Low-temperature optical and thermal properties of AgI-based phosphate glasses

Autor: Antonino Bartolotta, C. Armellini, Gaspare Tripodo, Flavio Rossi, Aldo Fontana, Giovanna D'Angelo

Publikováno v: Philosophical Magazine B. 79:2073-2080

Brillouin and Raman scattering measurements on (AgI) x (AgPO3) 1-x glasses are compared with low-temperature specific heat measurements. The direct comparison of the Brillouin shift and the freauency of the boson peak maximum shows that these feature
