## Description

- description: The physical and structural parameters of glass depend on its preparation
    conditions. Fictive temperature, Tf, is a standard for glass obtained from the
    super-cooled liquid. Although the Tf value is discussed from the viewpoint of
    structural relaxation defined by infrared vibration, there should be structural
    correlations at the longer ranges, which are worthy of exploration. Here, we demonstrate
    the structural change of the intermediate range in SiO2 glasses with different
    Tf values using X-ray and neutron diffraction, inelastic light scattering, and
    positron annihilation spectroscopy. By annealing the SiO2 glasses, i.e., decreasing
    Tf, an increase in the first sharp diffraction peak (FSDP) heights and narrowing
    of the peak width are observed. Differential structure factor ΔS(Q) of neutron
    diffraction reveals a formation of the thermally derived O–O inter-tetrahedral
    correlation in high-Tf glass. Spectroscopic analyses (Raman scattering, stimulated
    Brillouin scattering, and positron annihilation spectroscopy) suggest that a certain
    structural change has occurred in the SiO2 glass exhibiting higher Tf values,
    confirming that these approaches can be used as probes for structural ordering.
    Considering ΔS(Q) of neutron diffraction, it is suggested that the structural changes
    in SiO2 glass with higher Tf values observed by spectroscopy correlate with oxygen-related
    structural change in the intermediate range. Since the observed structures of
    each analysis are different, these multiscale and quantitative examinations are
    important for precise examination of various random materials.
