In this review, the major achievements and research and development (R&D) trends from the last decade in the field of single crystal scintillator materials are described. Two material families are included, namely, those of halide and oxide compounds. In most cases, the host crystals are doped with Ce3+, Pr3+ or Eu2+ rare earth ions. Their spin‐ and parity‐allowed 5d–4f transitions enable a rapid scintillation response, on the order of tens to hundreds of nanoseconds. Technological recipes, extended characterization by means of optical and magnetic spectroscopies, and theoretical studies are described. The latter provide further support to experimental results and provide a better understanding of the host electronic band structure, energy levels of specific defects, and the emission centers themselves. Applications in medical imaging and dosimetry, security measures, high‐energy physics and the high‐tech industry, in which X(γ)‐rays or particle beams are used and monitored, are recognized as the main driving factor for R&D activities in this field.

“…Rare earth metal ion‐doped materials have been in the focus for many years because of their optical properties. The applications range from color TV to fluorescent tubes, fiber amplifiers, biological sensors, lasers, scintillators, pc‐LEDS, novel quantum information technology materials, and many more . A number of different compound classes has been investigated as host lattices, such as halides,, phosphates, molybdates, borates, sulfates, silicates, sulfides, oxynitrides, or nitrides , .…”

The optical properties of rare earth ions in different inorganic host materials, for instance oxides, silicates, borates, or nitrides, have been used in applications for many years, from color TV to fluorescent tubes, lasers, or pc-LEDs. However, rare earth metal ion-doped hydrides have not really been considered as host lattices and up to now only been studied in a relatively small number of investigations. Yet, for certain metal hydrides these studies, e.g., allowed the determination * Dr. N. Kunkel 137of the crystal field strength and nephelauxetic effect of the hydride anion using the Eu 2+ 5d excited state. In air-sensitive hydrides, the use may be restricted to fundamental studies and local probes. But recently more and more air-stable mixed anionic hydrides have been discovered, which may serve as hosts. This short review summarizes the synthesis and characterization of rare earth metal ion-doped hydrides reported so far.

“…Its emission can be tuned from yellow to red by adjusting its chemical environment, since the electronic transitions of these cations are not f-f and are thus strongly affected by the crystal field [166]. Most of the time, UV radiation is required as excitation source, but some nitride-and sulfide-based phosphors can be excited with visible light [289,290] , Ti 4+ and main group elements such as Bi 3+ have been also reported as activators [20].…”

Rare earth based nanostructured materials: synthesis, functionalization, properties and bioimaging and biosensing applications

et al. 2017

Abstract:Rare earth based nanostructures constitute a type of functional materials widely used and studied in the recent literature. The purpose of this review is to provide a general and comprehensive overview of the current state of the art, with special focus on the commonly employed synthesis methods and functionalization strategies of rare earth based nanoparticles and on their different bioimaging and biosensing applications. The luminescent (including downconversion, upconversion and permanent luminescence) and magnetic properties of rare earth based nanoparticles, as well as their ability to absorb X-rays, will also be explained and connected with their luminescent, magnetic resonance and X-ray computed tomography bioimaging applications, respectively. This review is not only restricted to nanoparticles, and recent advances reported for in other nanostructures containing rare earths, such as metal organic frameworks and lanthanide complexes conjugated with biological structures, will also be commented on.
