Structural Subnanovoids in Silica-Based Glasses Probed by Positronium

Structural subnanovoids in silica-based glasses with various glass former contents are systematically studied using positronium (Ps) as a probe. The average sizes of the structural subnanovoids are estimated from the 2D-ACAR (two-dimensional angular correlation of positron annihilation radiation) mo...
