Homogeneous and inhomogeneous contributions to the luminescence linewidth of point defects in amorphous solids: Quantitative assessment based on time-resolved emission spectroscopy
Michele D Amico, Fabrizio Messina, Marco Cannas +2
The article describes an experimental method that allows to estimate the inhomogeneous and homogeneous linewidths of the photoluminescence band of a point defect in an amorphous so…
Role of hydrogen on the generation and decay of point defects in amorphous silica exposed to UV laser radiation
F. Messina
This experimental PhD work deals with the generation and transformation processes of point defects induced by UV laser irradiation on amorphous silicon dioxide (silica). The invest…
Character of the reaction between molecular hydrogen and silicon dangling bond in amorphous SiO_2
F. Messina, M. Cannas
The passivation by diffusing H2 of silicon dangling bond defects (E' centers, induced by laser irradiation in amorphous SiO_2 (silica), is investigated in situ at several temperatu…
Photochemical generation of E' centre from Si-H in amorphous SiO2 under pulsed ultraviolet laser radiation
F. Messina, M. Cannas
In situ optical absorption spectroscopy was used to study the generation of E' centres in amorphous SiO_2 occurring by photo-induced breaking of Si-H groups under 4.7eV pulsed lase…
