Structure, luminescence and magnetic properties of an erbium(iii) β-diketonate homodinuclear complex

Abstract

The photoluminescence properties and field-induced single-molecule-magnetic behavior of a novel erbium(iii) β-diketonate homodinuclear complex, [Er2(nd)6(μ-bpm)] (nd = 2,4-nonanedione and bpm = 2,2′-bipyrimidine), are presented.

Synthesis, Crystal Structures, and Optical and Magnetic Properties of Samarium, Terbium, and Erbium Coordination Entities Containing Mono-Substituted Imine Silsesquioxane Ligands

“…Upon cooling, the χ m T for both compounds remains relatively constant down to 100 K, below which it begins a steeper reduction to 4.27 cm 3 mol –1 K ( 3 ) and 7.08 cm 3 mol –1 K ( 4 ) at 1.8 K. The gradual decrease of χ m T upon cooling can be explained by a progressive depopulation of excited Stark sublevels because of the ligand field effects. This suggests the presence of significant magnetic anisotropy characteristics for lanthanide­(III)-containing coordination entities. − Such behavior of 3 and 4 can also be attributed to weak intermolecular interactions. The plot of χ m –1 versus T obeys the Curie–Weiss law in the whole temperature range with a negative Weiss constant θ = −3.52 K ( 3 ) and −1.47 K ( 4 ).…”

Experimental and theoretical study of magnetic field induced photoluminescence enhancement in Er3+:YVO4 crystals

“…Rare earth luminescent materials, such as Eu 3+ -and Er 3+doped materials, have broad applications in lighting, displays, and sensing, owing to their ability to emit photons in both visible and mid-infrared regions [1][2][3][4][5]. Additionally, lanthanide ions have been considered as prospective elements for qubits and quantum storage in quantum computing in the last few years [6][7][8][9]. Thus, a fundamental understanding of the luminescence physics of rare earth ion doped materials is of vital importance for exploring new applications.…”
