Optical Absorption and Electron Paramagnetic Resonance of the E'-alpha Center in Amorphous Silicon Dioxide
G. Buscarino, R. Boscaino, S. Agnello +1
We report a combined study by optical absorption (OA) and electron paramagnetic resonance (EPR) spectroscopy on the E'-alpha point defect in amorphous silicon dioxide (a-SiO2). Thi…
Optical properties of Ge-oxygen defect center embedded in silica films
F. Messina, S. Agnello, R. Boscaino +3
The photo-luminescence features of Ge-oxygen defect centers in a 100nm thick Ge-doped silica film on a pure silica substrate were investigated by looking at the emission spectra an…
Influence of hydrogen on paramagnetic defects induced by UV laser exposure in natural silica
F. Messina, M. Cannas, R. Boscaino
Diffusion limited reactions of point defects were investigated in amorphous SiO2 exposed to UV laser light. Electron spin resonance and in situ absorption measurements at room temp…
H(II) centers in natural silica under repeated UV laser irradiations
F. Messina, M. Cannas, R. Boscaino
We investigated the kinetics of H(II) centers (=Ge'-H) in natural silica under repeated 266nm UV irradiations performed by a Nd:YAG pulsed laser. UV photons temporarily destroy the…
