“…13 The lifetimes of the Yb( 3 P 1 ) state in RG matrices have been recently measured by the Argonne group. 15 It was found that the Yb/Ar emission, averaged with the intensity profile over the 543-600 nm range, decays exponentially at a rate of 1.8 × 10 6 s −1 , close to the gas-phase value of 1.16 × 10 6 s −1 . 16 Moreover, attempts have been made to identify the emission from the metastable Yb 3 P 0 or 3 P 2 states.…”

“…39 This coupling has effectively been demonstrated for Yb through the measurements of the 3 P 1 and 3 P 0 lifetimes in the RGs. 15 We therefore take the populations n v , n b , and n r as proportional to the amplitudes of the 6s6p 3 P 1 violet, blue, and red emission peaks, respectively, further assuming that the overlap between each Gaussian peak is small.…”

The low-lying electronic states of Yb isolated in a solid Ar matrix grown at 4.2 K are characterized through absorption and emission spectroscopy. Yb atoms are found to occupy three distinct thermally stable trapping sites labeled "red," "blue," and "violet" according to the relative positions of the absorption features they produce. Classical simulations of the site structure and relative stability broadly reproduced the experimentally observed matrix-induced frequency shifts and thus identified the red, blue, and violet sites as due to respective single substitutional (ss), tetravacancy (Tv), and hexavacancy (Hv) occupation. Prolonged excitation of the (1)S → (1)P transition was found to transfer the Yb population from hv sites into Tv and ss sites. The process showed reversibility in that annealing to 24 K predominantly transferred the Tv population back into Hv sites. Population kinetics were used to deduce the effective rate parameters for the site transformation processes. Experimental observations indicate that the blue and violet sites lie close in energy, whereas the red one is much less stable. Classical simulations identify the blue site as the most stable one.

“…Studies of atomic species isolated in rare gas (RG) solids are of interest in many fundamental and applied respects. For atomic physics, they complement characterization of the interatomic interactions and electronic energy transfer pathways [1], can give atomic structure parameters unavailable from gas-phase experiments [2], and occasionally provide highly sensitive detection schemes [3]. For solid state physics and chemistry, they serve as the models of the structure, mobility and electronic properties of the point defects, as well as of the reactivity in solids [4][5][6].…”

Stable atomic trapping sites in the Lennard-Jones face-centered cubic Ar crystals are investigated by means of the global optimization strategy and convex hull concept for thermodynamic stability. Five generic site types are found in full accord with crystallographic intuition: interstitial within tetrahedral and octahedral hollows and substitutions, single, tetra-and hexavacancy. Their identities are established by radial distribution function analysis. Stability regions of these sites are mapped into the space of Lennard-Jones parameters of the guest-host interatomic interaction. Predictions made for the number and types of the stable sites for selected atoms (H, Mn, Na, Yb, Eu, Ba) are found to be in line with the results of more sophisticated models and matrix isolation spectroscopy experiments.

“…At the same time, the Ne crystal is a less perturbing envi-ronment than the heavier RGs. Isolated in it, the Yb electronic structure is still qualitatively the same as in vacuum, while the lifetimes of excited states are not significantly different [10,11]. Based on these observations, single atom detection of Yb in sNe would appear feasible, which could then be extended for use in detecting rare nuclear reactions [22].…”

“…Examples of systems studied specifically for these applications include alkali atoms in both solid RGs [8] and parahydrogen [9], Yb atoms in solid Ne [10,11] and Tm atoms in solid Ar and Kr [12]. For these species, medium effects generally broaden linewidths and shift transition frequencies by several hundred wavenumbers [8].…”

We present an experimental and theoretical study of the absorption and emission spectra of Yb atoms in a solid Ne matrix at a resolution of 0.025 nm. Five absorption bands were identified as due to transitions from the 4f 14 5d 0 6s 2 1 S0 ground state configuration to 4f 14 5d 0 6s6p and 4f 13 5d 1 6s 2 configurations. The two lowest energy bands were assigned to outer-shell transitions to 6s6p 3 P1 and 1 P1 atomic states and displayed the structure of a broad doublet and an asymmetric triplet, respectively. The remaining three higher-frequency bands were assigned to inner-shell transitions to distinct J = 1 states arising from the 4f 13 5d 1 6s 2 configuration and were highly structured with narrow linewidths. A classical simulation was performed to identify the stability and symmetry of possible trapping sites in the Ne crystal. It showed that the overarching 1+2 structure of the high frequency bands could be predominantly ascribed to crystal field splitting in the axial field of a 10atom vacancy of C4v symmetry. Their prominent substructures were shown to be manifestations of phonon sidebands associated with the zero-phonon lines on each crystal field state. Unprecedented for a metal-rare gas system, resolution of individual phonon states on an allowed electronic transition was possible under excitation spectroscopy which reflects the semi-quantum nature of solid Ne. In contrast to the absorption spectra, emission spectra produced by steady-state excitation into the 1 P1 absorption band consisted of simple, unstructured fluorescence bands.
