Boson peak and structural heterogeneity in ternary SiO2-Al2O3‐B2O3 glasses
Abstract
<jats:title>Abstract</jats:title><jats:p>We use low‐temperature heat capacity, low‐frequency Raman scattering, and THz time domain spectroscopy in order to scale the vibrational density of states and the Boson peak in SiO<jats:sub>2</jats:sub>‐Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>‐B<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> Yb‐laser host glasses. When substituting B<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> for SiO<jats:sub>2</jats:sub> at constant Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> dopant level, we find an optimal value for the ratio of B/Al in terms of mixture stability, at which the excess in the electron donor capability of Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> (relative to the SiO<jats:sub>2</jats:sub> backbone) is compensated by the more acidic B<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>. At this composition, Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> plays a mediating role in the structure of aluminoborosilicate glasses, facilitating dissolution of Yb<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> and admixture of B<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> into the SiO<jats:sub>2</jats:sub> network.</jats:p>
