“…2 Á cm 2 , R L is the distance between the regions of the hybrid emitting centers or the ligand molecules in which the donor states are localized, the quantities a 0 J 0 U ðlÞ aJi are reduced matrix elements of the unit tensor operators U(l), and V l e:d represents the forced-electric-dipole contribution to the 4f-4f intensity parameters. In Equation 26, S 0 is the total spin operator of Eu 3þ , m Z is the z component of the electric-dipole operator, s 0 m (m ¼ 0, AE1) is a spherical component of the spin operator, both for the hybrids or ligand electrons (respectively in the calculus of the W e hybrid-to-Eu 3þ or ligand-to-Eu 3þ energy-transfer rates), and s 0 is a distancedependent screening factor.

Lanthanide‐Containing Light‐Emitting Organic–Inorganic Hybrids: A Bet on the Future

Interest in lanthanide-containing organic-inorganic hybrids has grown considerably during the last decade, with the concomitant fabrication of materials with tunable attributes offering modulated properties. The potential of these materials relies on exploiting the synergy between the intrinsic characteristics of sol-gel derived hosts (highly controlled purity, versatile shaping and patterning, excellent optical quality, easy control of the refractive index, photosensitivity, encapsulation of large amounts of isolated emitting centers protected by the host) and the luminescence features of trivalent lanthanide ions (high luminescence quantum yield, narrow bandwidth, long-lived emission, large Stokes shifts, ligand-dependent luminescence sensitization). Promising applications may be envisaged, such as light-emitting devices, active waveguides in the visible and near-IR spectral regions, active coatings, and bio-medical actuators and sensors, opening up exciting directions in materials science and related technologies with significant implications in the integration, miniaturization, and multifunctionalization of devices. This review provides an overview of the latest advances in Ln(3+)-containing siloxane-based hybrids, with emphasis on the different possible synthetic strategies, photoluminescence features, empirical determination.

“…Because of their unusual luminescent properties, triply charged lanthanide ions find many applications in different scientific and technological fields such as the lighting industry, photonics, laser physics and biotechnology, see e.g., [1][2][3][4][5][6]. If we except La 3+ , all these ions are characterized by a ground electronic configuration of the type [Xe]4f k with k varying from 1 (Ce 3+ ) to 14 (Lu 3+ ), which is mainly responsible for their interesting photophysical properties such as long-lived luminescence and sharp absorption and emission lines.…”

Abstract:A new set of radiative decay parameters (oscillator strengths, transition probabilities) for spectral lines in triply ionized thulium (Tm IV) has been obtained within the framework of the pseudo-relativistic Hartree-Fock (HFR) approach. The effects of configuration interaction and core-polarization have been investigated in detail and the quality of the results has been assessed through a comparison between different HFR physical models. The spectroscopic data listed in the present paper cover electric dipole as well as magnetic dipole and electric quadrupole transitions in a wide range of wavelengths from extreme ultraviolet to near infrared.
