“…The results achieved with the advanced Li 2 MoO 4 cryogenic scintillator [311] triggered an extensive R&D on Li 2 MoO 4 scintillating bolometers recently realized within the ISOTTA and LUMINEU projects [74,345,[475][476][477]. Currently, several R&D activities on the Li 2 MoO 4 development for scintillating bolometers are ongoing world-wide: in France (CLYMENE project [478][479][480][481]), in the Republic of Korea [482][483][484][485], in China [486,487], in the United States [488,489], in Ukraine [490], in addition to the existing crystal growth technologies in Russia [74,311,473,476,[491][492][493][494]. Most of these activities were and are considered part of R&D programs towards large-scale bolometric DBD search experiments CUPID [82,495,496] and AMoRE [81,483].…”

Inorganic crystal scintillators play a crucial role in particle detection for various applications in fundamental physics and applied science. The use of such materials as scintillating bolometers, which operate at temperatures as low as 10 mK and detect both heat (phonon) and scintillation signals, significantly extends detectors performance compared to the conventional scintillation counters. In particular, such low-temperature devices offer a high energy resolution in a wide energy interval thanks to a phonon signal detection, while a simultaneous registration of scintillation emitted provides an efficient particle identification tool. This feature is of great importance for a background identification and rejection. Combined with a large variety of elements of interest, which can be embedded in crystal scintillators, scintillating bolometers represent powerful particle detectors for rare-event searches (e.g., rare alpha and beta decays, double-beta decay, dark matter particles, neutrino detection). Here, we review the features and results of low-temperature scintillation detection achieved over a 30-year history of developments of scintillating bolometers and their use in rare-event search experiments.

BACKGROUND: Dysprosium oxide (Dy2O3) gathers a set of profitable properties, whose wide range of applicability includes from energy to astronomy. Particle characteristics influence directly the formation and features of materials by colloidal processing. The main purpose of this paper is to carry out a powder characterization of Dy2O3 particles. The findings reported are worthwhile parameters to advance in the formulation of new smart materials for radiation dosimetry. METHODS: Dy2O3 powders were characterized by XRD, PCS, SEM, pynometric density (ρ), FTIR, ICP, EPR, and zeta potential (ζ). RESULTS: The powdered samples exhibited as main features, cubic C-type structure in accordance with the RE-polymorphic diagram, a mean particle size distribution with d50 of 389nm, and pynometry density of 7.94g.cm-3. The EPR spectra revealed three distinct peaks p1, p2, and p3, with the following g values 2.3121, 2.1565, and 2.1146, respectively. In addition, the nanoparticles presented high stability at pH 5.5 and ζ-value of |49.7|mV. CONCLUSION: The powder characterization of Dy2O3 powders was reported. The results achieved in this study may be considered worthwhile parameters to advance in the formulation of Dy2O3 based materials for radiation dosimetry.
