“…The mixed crystals of garnet structures demonstrate spectacular progress in improved scintillation properties. [2] Particularly interesting are mixed garnets, which exhibit a high light yield of up to 70 000 photons MeV −1 , have a luminescence decay time shorter than 100 ns, and emission band peaks at 520 nm, which perfectly match the sensitivity spectrum of the conventional Silicon Photo-Multipliers (SiPMs). [11] Novel gadolinium containing scintillation materials can become the scintillators of choice in high-resolution γ -radiation spectrometry and compete with halide scintillators recently developed for this purpose.…”

The search for engineering approaches to improve the scintillation properties of Gd3Al2Ga3O12 crystals and enable their production technology is of current interest. This crystal, while doped with Ce, is considered a good multi‐purpose scintillation material for detecting gamma‐quanta and neutrons. It is observed that co‐doping with Mg affected intrinsic defects in the crystal structure that create shallow electronic traps. Other point structure defects, which are based on local variations of the crystal stoichiometry, are significantly diminished by use of a co‐precipitated raw material. Nano‐structuring of the raw material enables production of a homogeneous precursor mixture for growing a crystal with minimal evaporation of Ga from the melt. The demonstrated nano‐engineering approach increased the light yield from the crystal by approximately 20%, enabling its applications in well logging.

“…Let me say from the beginning that this paper was motivated by second thoughts: indeed my research deals mostly with the photoelastic properties of scintillating crystals, that is crystals that convert ionizing radiation into photons within the visible range. Massive scintillating crystals were used to detect particle collisions in the CMS calorimeter at CERN, Geneva [1] and shall be used in the FAIR accelerator at GSI, Darmstadt [2] and can also be used in security and medical imaging devices. Amongst many other problems concerning quality control and efficiency, one of the major issues related to the prolonged use of these crystals is the radiation damage that displaces atoms and reduces crystal efficiency and the radiation/photons ratio (see, e.g., [3]).…”

We study the coupled macroscopic and lattice wave propagation in anisotropic crystals seen as continua with affine microstructure (or micromorphic). In the general case, we obtain qualitative information on the frequencies and the dispersion relations. These results are then specialized to crystals of the tetragonal point group for various propagation directions: exact representation for the acoustic and optic frequencies and for the coupled vibrations modes are obtained for propagation directions along the tetragonal c-axis.

“…Scintillators are materials that can convert ionizing radiations (like X-rays) into visible light [1]. Due to this property, these materials are used in ionizing radiations detection and are applied in high-energy physics, dosimetry and medical imaging technologies [2][3][4].…”

Sodium decatungstoeuropate, Na 9 [Eu(W 5 O 18) 2 ]•14H 2 O, is a promising material to convert X-ray into visible light. In this work, temperature and exposure time-dependent scintillation of the Na 9 [Eu(W 5 O 18) 2 ]•14H 2 O sample under X-ray excitation were evaluated. Light emission intensity decreases along with X-ray exposure time, probably due to electronic defects at (W 5 O 18) 6groups, leading to a lower efficiency of the LMCT (O→W) process, which is determinant in the scintillation mechanism of this material. After X-ray exposition, there is a partial recovery of the initial emission intensity, indicating that defects created are reversible. With temperature increasing, changes in the emission spectra evidence the decreasing of the local symmetry around the Eu 3+ ions, caused by reticular vibration and dehydration process. The luminescence intensity dependence with temperature suggests the possibility to use this material as molecular thermometer in two different temperatures ranges.
