Decomposition Process of Carboxylate MOF HKUST-1 Unveiled at the Atomic Scale Level
Michela Todaro, Gianpiero Buscarino, Luisa Sciortino +6
HKUST-1 is a metal-organic framework (MOF) which plays a significant role both in applicative and basic fields of research, thanks to its outstanding properties of adsorption and c…
Ultrafast Large Angle Beamstrahlung Monitor
Salvatore Di Carlo, Fabrizio Messina
The analysis of beamstrahlung radiation, emitted from a beam of charged particles due to the electromagnetic interaction with a second beam of charged particles, provides a diagnos…
Temperature dependence of reflectivity of amorphous silicon dioxide: Evidence of delocalized excitons weakly scattered by phonons
E. Vella, F. Messina, M. Cannas +1
We studied the reflectivity spectra of amorphous silicon dioxide detected under vacuum UV synchrotron radiation as a function of temperature between 10 and 300 K. Kramers-Kronig di…
Evidence of delocalized excitons in amorphous solids
Fabrizio Messina, Eleonora Vella, Marco Cannas +1
We studied the temperature dependence of the absorption coefficient of amorphous SiO in the range from 8 to 17.5~eV obtained by Kramers-Kronig dispersion analysis of reflectivi…
Photoluminescence dispersion as a probe of structural inhomogeneity in silica
Michele D'Amico, Fabrizio Messina, Marco Cannas +2
We report time-resolved photoluminescence spectra of point defects in amorphous silicon dioxide (silica), in particular the decay kinetics of the emission signals of extrinsic Oxyg…
Isoelectronic series of oxygen deficient centers in silica: experimental estimation of homogeneous and inhomogeneous spectral widths
Michele D'Amico, Fabrizio Messina, Marco Cannas +2
We report nanosecond time-resolved photoluminescence measurements on the isoelectronic series of oxygen deficient centers in amorphous silica, Si-ODC(II), Ge-ODC(II) and Sn-ODC(II)…
