Synthesis of Y3Al5O12:Ce3+ phosphor in the Y2O3–Al metal–CeO2 ternary system

Structural and spectroscopic properties of new noncentrosymmetric self-activated borate Rb3EuB6O12 with B5O10 units

“…Under the selected technological conditions, synthesis resulted in the agglomerates 5-20 m in size formed by strongly coalescent individual grains with diameter below 1 m. This micromorphology is common in oxides when temperature/time conditions used for the solid state reaction are high enough for the active grain interdiffusion [16,34,37,43,44]. It should be pointed that the Rb3EuB6O12 particles possessed strong charging effect during SEM measurements and this verifies their very low conductivity common for the oxides without oxygen vacancies.…”

New development of radiopure ZnWO4 crystal scintillators

“…Formerly, some crystals were produced by the Institute for Scintillation Materials (ISMA, Kharkiv, Ukraine) and, later on, a collaboration with the Nikolaev Institute of Inorganic Chemistry (Novosibirsk, Russia) has started. In this last Collaboration a R&D to produce ultra-radiopure ZnWO 4 by using the low-thermal gradient Czochralski technique in a platinum crucible is ongoing [22]. The produced crystals have been deployed in the underground facility DAMA/R&D at the Gran Sasso laboratory (LNGS) [11,12,20,21].…”

“…This pulse shape discrimination capability can potentially be of interest not only for a DM experiment but also for double beta decay searches. The ZnWO 4 offers also a high atomic weight and the possibility to realize single crystals with masses of some kg [22]. Moreover, the presence of three target nuclei with very different masses (Zn, W and O) makes these scintillators sensitive to both small and large mass DM candidates, as also the NaI(Tl) is.…”

Exploration of structural, thermal and spectroscopic properties of self-activated sulfate Eu2(SO4)3 with isolated SO4 groups

“…To fill this gap, in the present work, the polycrystalline powder of Eu2(SO4)3 has been synthesized and the crystal structure of the sulfate has been determined for the first time. It might be well to point that much research on synthesis of materials for various applications by different methods, including the green chemistry approach, were conducted resently [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63]. However, to provide synthesis of stoichiometric Eu2(SO4)3 compound, the precipitation approach was used in the present study.…”
