C59N magnetic fullerenes were formed inside single-wall carbon nanotubes by vacuum annealing functionalized C59N molecules encapsulated inside the tubes. A hindered, anisotropic rotation of C59N was deduced from the temperature dependence of the electron s ...
Light emission during the collision of ions and cluster ions on a metal surface covered by rare gas matrices of variable thickness is reported. The light intensity as a function of distance from the metal surface follows the classical image dipole theory. ...
We describe a new UV-Vis absorption setup designed to measure with improved sensitivity the absorption spectra of size-selected small metal clusters embedded in rare gas matrices. We aim at studying the electronic structure of clusters of different materia ...
Thin films of tantalum oxynitride were prepared by reactive magnetron sputtering using a Ta target and N2 and O2 as reactive gases. The nitrogen flow was kept constant while the oxygen flow was pulsed periodically. The film composition evolves progressivel ...
Patterns of noble-metal structures on top of self-assembled monolayers (SAMs) on Au and SiO2 substrates have been prepared following two approaches. The first approach consists of pulsed laser deposition (PLD) of Pt, Pd, Au, or Cu through nano- and microst ...
We report absorption spectra for Ag7, Ag9, and Ag11 in an argon matrix grown at a temperature of 28 K and compare them with previous spectra of the same species measured in matrices of argon grown at lower temperatures as well as in neon matrices. We discu ...
The absorption spectra of small silver and gold clusters are presented. The experimental technique consists in depositing clusters in an argon matrix which is illuminated with white light. By collecting the outcoming light from the matrix and by analysing ...
ELMy H-mode experiments at JET in 2000/mid-2002 have focused on discharges with normalized parameters for plasma density, energy confinement and beta similar to those of the ITER Q(DT) = 10 reference regime (n/n(GW) similar to 0.85, H-98(y,H-2) similar to ...
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 ...
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 ...
