First test of a li2wo4(mo) bolometric detector for the measurement of coherent neutrino-nucleus scattering / A. Aliane, I. C. Avetissov, O. P. Barinova et al. // Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. — 2020. — Vol. 949. — P. 162784. The first observation of coherent elastic neutrino-nucleus scattering (CEνNS), reported by the COHERENT Collaboration in 2017, paved the way for a new generation of experiments using reactor ν¯e and aiming at precisely measuring this process. In this context, the BASKET (Bolometers At Sub-KeV Energy Thresholds) R&D project investigates the use of cryogenic detectors for a re- actor CEνNS experiment. This article reports on the first test of a Mo-doped lithium tungstate scintillating bolometer (018×7 mm, 8 g), performed in an aboveground laboratory at CSNSM, Orsay (France). The detector bolometric performance (energy and time response, particle identification capabilities) and radiopurity have been studied and confirm the promising potential of lithium tungstate-based bolometric detectors for the measurement of CEνNS at reac- tors.

Crystal growth and luminescent properties of lina5mo9o30 / V. A. Sukharev, A. P. Sadovskiy, E. A. Sukhanova et al. // Journal of Crystal Growth. — 2019. — Vol. 519. — P. 35–40. LiNa5Mo9O30 (LNM) single crystal has been grown by the Czochralski technique with 1-10 K/cm temperature gradient. A numerical simulation of heat-mass transfer has been carried out. The melt viscosity of 25 cPz was measured at 570oC and 3.25 g/cm3 melt density. The structural and optical quality of the LNM crystal was analyzed by X-ray topography and dynamic holography. The luminescent properties of LNM were studied in the temperature range 4.2 – 300 K under photo- and electron excitation. Two emission bands peaking at 620 and 700 nm were found and ascribed to the emission of excitons trapped at MoO6 and MoO5 complexes, respectively. The LNM crystal demonstrated a laser damage threshold as high as 80 J/cm2 (16 GW/cm2). [ DOI ]

Fundamentals of organometallic electrophosphors synthesis under controlled temperature and ligand partial pressure / R. Avetisov, A. Akkuzina, N. Kozlova et al. // Dyes and Pigments. — 2019. — Vol. 161. — P. 482–488. A new technique for analysis of "Ligand partial pressure - Temperature" diagram has been developed for the organometallic phosphor tris(8-hydroxyquinoline) M (M=Al, Ga, In). The detection of mono- and bivariant equilibriums within the p8-Hq-T diagram has been done using simultaneous measurements of photoluminescence and reflection spectra of a condense phase under controlled p8-Hq and T. Using preparations with the purity better than 99.999 wt% the corresponding p8-Hq-T diagrams have been plotted in the temperature range from 350 K to the maximum melting temperatures of the compounds. The homogeneity ranges of different polymorphs have been determined. For the different polymorphs it have been demonstrated that changing the synthesis conditions within the homogeneity range of the phases resulted to the significant changes of the nonstoichiometry, chemical activities and electroluminescent properties of the OLED structures, prepared on the base of β-Mq3.

Growth of k2co(so4)2*6h2o crystals using low-frequency axial vibration control technique / I. M. Ermochenkov, E. V. Dubovenko, A. P. Sadovski, I. C. Avetisov // Crystallography Reports. — 2019. — Vol. 64, no. 2. — P. 360–362. K2Co(SO4)2 · 6H2O crystals have been grown by lowering temperature with the formation of controlled mass transfer by means of low-frequency harmonic oscillations of a chemically inert body immersed in a solution, i.e., by a technique of low-frequency axial vibration control technique. It is shown that application of this technique allows one to increase the volume growth rate by a factor of ∼2 and improve the structural quality of crystals, i.e., to decrease the dislocation density on different faces by a factor of 10–100. An analysis of the transmission spectra in the range of 200–400 nm showed that the grown crystals are more transparent (by 26%) than the crystals grown in the absence of vibrations. [ DOI ]

Luminescent hybrid materials based on metal-organic phosphors in pbf2 powder and pbf2-containing glass matrix / O. B. Petrova, K. I. Runina, M. N. Mayakova et al. // Optical Materials. — 2019. — Vol. 88. — P. 378–384. The new hybrid materials (HM's) are based on the phosphors used in OLED technology in inorganic PbF2-containing matrices: PbF2 powders and low melting PbF2-based oxyfluoride glasses, were synthesized. We used highly effective thermostable phosphors: 4,4,5,5,6,6,7,7,8,8,9,9,9-tridecafluoro-1- (1-methyl-1H-pyrazol-4-yl)nonane-1,3-dione - (1,10-phenanthroline) europium (III), 8-hydroxyquinoline complexes with metals and the individual organic ligand – 4,4,4-trifluoro-1- (2-naphthyl) butane-1,3-dione. Powdered HM's were prepared by co-precipitation from aqueous solutions. The effect of organic molecules or molecular fragments on dimension and morphology of precipitated PbF2 particles, the luminescence properties of HM's were investigated for the samples obtained directly after the precipitation-drying procedure, and after the powders' calcination procedure. The change in the photoluminescence spectra after the heat treatment of the powders is caused by the proceeding of the exchange reaction between the metal complex and the matrix with the formation of Pb-complexes of different coordination is shown. HM (glasses PbF2eB2O3, PbF2eB2O3eSiO2 or PbF2eB2O3eSiO2eZnO phosphor) were obtained by the melt process in which the phosphor powder was submerged into the melt of the pre-synthesized glasses. [ DOI ]
