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 ]

Effect of inorganic matrix composition on luminescent properties of hybrid materials / K. I. Runina, V. A. Shmelyova, O. B. Petrova et al. // IEEE 2018 International Conference Laser Optics (ICLO) . — 2018. — P. 402–402. A luminescent organic-inorganic hybrid materials based on metal complexes organic phosphors and low-melting lead fluoroborate and fluoroborosilicate glasses have been synthesized. All hybrid materials showed a wide luminescence band in the range 400-700 nm. The effect of the matrix composition on the intensity and the contour of the luminescence line of hybrid materials were studied. [ DOI ]

Hot-pressed production and laser properties of znse:fe 2 / R. I. Avetisov, S. S. Balabanov, K. N. Firsov et al. // Journal of Crystal Growth . — 2018. — Vol. 491. — P. 36–41. A new approach for fabrication of laser elements in form of plates based on ZnSe:Fe⁠2+ with undoped faces, combining the advantages of hot pressing and diffusion techniques has been proposed. CVD-ZnSe was used as a host material. 1μm Fe film was deposited by electron-beam technique on one side of the polished CVD-ZnSe plate (20mm in diameter and 2mm in thickness). The elements were stacked in contact by iron surfaces, placed in a hot press-mold die, heated under vacuum to 1000oC, exposed during 60min with the application of 25MPa uniaxial pressure. The iron film was dissolved in ZnSe matrix and elements welded together. The samples were subjected to hot isostatic pressing (HIP) during 29h at 100MPa argon pressure and 1300oC. The influence of sintering and HIP processing conditions on local morphology and properties of the interface of welded elements was studied by SEM, TEM and optical microscopy. For all composite elements the lasing was obtained at a pumping by HF-laser at RT with high efficiency around 40%. The proposed technique removes restrictions on the size of laser elements and appears to be very promising for the management of the distribution profile of the doping component. [ DOI ]
