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. 162784–6. 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.

A novel candle light-style oled with a record low colour temperature / V. M. Korshunov, T. N. Chmovzh, E. A. Knyazeva et al. // ChemiComm. — 2019. — Vol. 55. — P. 13354–13357. The possibility of using a single light-emitting layer consisting of newly synthesized fluorescent small organic molecules of D–A–p–A type incorporated into a conductive matrix together with an electron conductive Alq3 layer in order to form radiation in candle light-style OLEDs was shown for the first time. A record low color temperature of 1722 K OLED radiation was achieved, which is by 80 K lower than that of the best devices reported previously. [ DOI ]

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 ]

Extra pure tellurium oxide for the growth of high quality paratellurite crystals / G. Mikhail, I. Anika, K. Andrew et al. // IOP Conference Series: Materials Science and Engineering. — 2019. — Vol. 613, no. 012021. — P. 1–6. llurium oxide (IV) single crystals are in demand materials for manufacturing acousto-optical devices optical fibers for IR wavelength range. The initial material for production of active and passive optical materials must have purity better than 99.999 wt% and extremely low concentration of the residual water. The main method of synthesis of TeO2 is oxidation in nitric acid followed by recrystallization from HCl is complicated, also amount of used high purity acids and waste are very high. Besides the residual water content is no less than 10 ppm. In the research we have developed the procedure for the synthesis of high-purity tellurium (IV) oxide without the usage of liquid oxidants. The process of oxidation of elementary Te was carried out in a flowing quartz glass reactor. Air oxygen was used as an oxidizing agent. The oxidation was conducted at 600-670oC during 24 hours. The produced material was a fine crystalline powder of acicular dendritic crystals of bright white color, identified as β-TeO2 due to X-ray. It was as pure as 5N7 due to ICP-MS. The beta-TeO2 crystal grown form the synthesized water-free preparation has demonstrated better optical properties towards the crystals grown from commercial TeO2, produced by the wet technology.

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.
