Optical properties of small metal clusters
This thesis is devoted to the study of the optical properties of small metal clusters and metal cluster organic compounds. For this purpose a ultra-high vacuum (UHV) experimental apparatus has been built which allows for the deposition of mass selected neu ...
EPFL2015Broadband extreme ultraviolet probing of transient gratings in vanadium dioxide
Nonlinear spectroscopy in the extreme ultraviolet (EUV) and soft x-ray spectral range offers the opportunity for element selective probing of ultrafast dynamics using core-valence transitions (Mukamel et al., Acc. Chem. Res. 42, 553 (2009)). We demonstrate ...
Optical Society of America2015Spectroscopy of 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA) attached to rare gas samples: Clusters vs. bulk matrices. II. Fluorescence emission spectroscopy
Wolfgang Harbich, Alexandre Rydlo, Stefan Minniberger, Matthieu Dvorak
The interaction between 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA) molecules and solid rare gas samples is studied by means of fluorescence emission spectroscopy. Laser-excited PTCDA-doped large argon, neon, and para-hydrogen clusters along wi ...
American Institute of Physics2012Ultraviolet-visible absorption of small silver clusters in neon: Ag-n (n=1-9)
Wolfgang Harbich, Sylvain Lecoultre, Alexandre Rydlo
We present optical absorption and fluorescence spectra in the UV-visible range of size selected neutral Ag-n clusters (n = 1-9) in solid neon. Rich and detailed optical spectra are found with linewidths as small as 50 meV. These spectra are compared to tim ...
American Institute of Physics2011Ultrafast Optical and X-ray Absorption Studies of Solvation Dynamics
Solvation dynamics, the process of solvent reorganization upon electronic excitation of a solute, is central to our understanding chemical reactions in liquid phase. Ultrafast optical studies of solvation dynamics have so far been carried out on polyatomic ...
EPFL2010The ultrafast structural response of solid parahydrogen: a complementary experimental/simulation investigation
Majed Chergui, Frank van Mourik
A complete characterization, based on fs pump-probe spectroscopy and mol. dynamics simulations, is presented of the ultrafast dynamics of electronic bubble formation in solid para-H2 upon impulsive excitation of impurity-doped sites, which correlate with t ...
2006Ultrafast structural dynamics in electronically excited solid neon. I. Real-time probing of the electronic bubble formation
Majed Chergui, Franco Vigliotti, Luigi Bonacina
The dynamics of electron bubble formation upon excitation of the A(3ss) Rydberg orbital of NO in solid Ne was studied by conventional spectroscopy and fs pump-probe spectroscopy. The fs pump pulse initiates the formation of a bubble by the expansion of the ...
2003Ultrafast structural dynamics in electronically excited solid neon. II. Molecular-dynamics simulations of the electronic bubble formation
Majed Chergui, Franco Vigliotti
Mol.-dynamics simulations of structural relaxation in electronically excited NO-doped solid neon are presented. The NO impurity is excited to its lowest A (3ss) Rydberg state, inducing a rearrangement of the surrounding medium in the form of a bubble, due ...
2003Structural dynamics in quantum solids. II. Real-time probing of the electronic bubble formation in solid hydrogens
Majed Chergui, Franco Vigliotti, Luigi Bonacina
The ultrafast dynamics of electronic bubble formation upon excitation of the A(3ss) Rydberg state of NO trapped in solid H2 and D2 was studied by femtosecond pump-probe spectroscopy. The evolution of the spherical bubble is followed in real time by a probe ...
2002Structural dynamics in quantum solids. I. Steady-state spectroscopy of the electronic bubble in solid hydrogens
Majed Chergui, Franco Vigliotti
The structural changes due to formation of electronic bubbles in solid D2 are studied by fluorescence, fluorescence-excitation, and fluorescence-depletion spectroscopy of the lowest Rydberg state, A 2S+(3ss), of the NO impurity. The A X band is strongly bl ...
