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.

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.

Optical properties transformation under laser treatment of hybrid organic-inorganic thin films / R. Saifutyarov, O. Petrova, I. Taydakov et al. // Physica Status Solidi (A) Applications and Materials. — 2019. — P. 1800647. [ DOI ]

The effect of borate glass matrix on the luminescence properties of organic–inorganic hybrid materials / M. O. Anurova, K. I. Runina, A. V. Khomyakov et al. // Physics and Chemistry of Glasses: European Journal of Glass Science and Technology Part B. — 2019. — Vol. 60, no. 4. — P. 140–145. Low melting lead fluoroborate, borosilicate and fluoroborosilicate glasses have been synthesised and their optical, mechanical and thermodynamic properties have been determined. The most transparent glasses were chosen as matrices for the synthesis of luminescent hybrid materials in which β-diketone complexes of lanthanides (Nd, Er and Yb) were used as organic constituents. All hybrid materials showed a wide luminescence band in the range 400–700 nm. [ DOI ]
