Absorption, emission and fluorescence-excitation spectra are reported for Hg atoms and Hg2 mols. in Ar, Kr, Xe and N2 matrixes upon excitation by synchrotron radiation in the 260-90 nm range. The fluorescence emitted from all levels issued from the 6s6p co ...
The noble gas krypton is shown to bind to crystallized proteins in a similar way to xenon [Schiltz, Prange & Fourme (1994). J. Appl. Cryst. 27, 950-960]. Preliminary tests show that the major krypton binding sites are essentially identical to those of xeno ...
The dynamics of electron bubble formation upon excitation of the A(3ss) Rydberg orbital of NO in solid Ne was studied by femtosecond pump-probe spectroscopy. The authors observe an ultrafast expansion of the bubble, followed by a vibrational recurrence in ...
Environmental effects on electronic states of small mols. in solid rare gases and in liqs. have severe consequences on the photochem.; examples for valence, Rydberg and ionic states as well as the connection to photochem. dry etching are treated. The repul ...
Fluorescence (phosphorescence) excitation spectra as well as luminescence spectra and decay times were investigated for NO in N2 and mixed N2/Kr matrixes. All Rydberg states rapidly relax to the ground state in mixed matrixes with the N2 molar fraction exc ...
Higher Rydberg states of NO trapped in rare gas matrixes were studied by inducing Rydberg-Rydberg transitions from the lowest A2S+ (3ss) Rydberg state and detecting its fluorescence depletion. This technique unravels Rydberg states, which cannot be accesse ...
The photoluminescence (PL) and PL-excitation (PLE) spectra of InyCa1-yAs/AlxGa1-xAs compressively strained V-groove quantum wires (QWR's) are compared to that of lattice-matched GaAs/AlyGa1-xAs QWR's with the same wire geometry. The PL is preferentially po ...
The ultrafast dynamics are reported of bubble formation following excitation of the A 2S+ 3ss(v = 0) Rydberg state of NO trapped in Ar matrixes. The study is carried out by a fs pump-probe technique. The detected signal is the depletion of Rydberg fluoresc ...
Rydberg-Rydberg transitions are induced by absorption from the lowest Rydberg state of NO A 2S+ (3ss) in Ar matrixes, which is excited by an ArF laser at 193.3 nm. The depopulation of the A(v = 0) level to higher Rydberg states is probed by depletion of it ...
Absorption, emission and excitation spectra of NO in N2 and mixed N2/Kr matrixes at various N2 concns. have been recorded by means of tunable synchrotron radiation and ArF laser excitation. The gas-to-matrix shifts, bandwidths and Stokes shifts of the lowe ...
