Spectroscopic parameters related to non bridging oxygen hole centers in amorphous-SiO2
L. Vaccaro, M. Cannas, B. Boizot
The relationship between the luminescence at 1.9 eV and the absorption bands at 2.0 eV and at 4.8 eV were investigated in a wide variety of synthetic silica samples exposed to diff…

Stimulated Nutation Echo: Dynamic and Decay Properties
G. Bimbo, R. Boscaino, M. Cannas +2
We study experimentally the dynamical and decay properties of the Stimulated Nutation Echo (SNE) in a two-level spin system. This is the signal which appears in the transient respo…

Luminescence properties of point defects in silica
Marco Cannas
The optical properties of point defects in as-grown natural silica are reviewed. Two emissions peaked at 4.2 eV ( band) and at 3.1 eV ( band), related to an absorption band…
