Influence of crystal growth conditions and carbothermal treatment on activator charge state in Ti:sapphire

Nizhankovskiy, S.V.; Sidelnikova, N.S.; Baranov, V.V. (Functional Materials, 2018)

Presented are the results of comparative studies of the influence of carbothermal treatment of the raw material (Al₂O₃ and TiO₂ powders) and reducing properties of the growth medium on the charge state of titanium ions in ...
Influence of melt convection on the dynamics and capture inclusions for growing oxide crystals by HDC

Naydenov, S.V.; Nizhankovskiy, S.V.; Tan′ko, A.V.; Grin′, L.A.; Baranov, V.V. (Functional Materials, 2015)

The main properties of motion of gas-vapor bubbles and impurity inclusions in hydrodynamic flows are considered. It is founded the criteria for the formation of the defective areas for crystal growth of oxide crystals by ...
Mechanism of AlN film formation at thermochemical nitridization of sapphire

Kaltaev, Kh.Sh.-ogly; Nizhankovskiy, S.V.; Sidelnikova, N.S.; Rom, M.A.; Dan'ko, A.Ya.; Dobrotvorskaya, M.V.; Belyaev, A.Ye.; Strelchuk, V.V.; Kolomys, A.F. (Functional Materials, 2011)
Optical and laser properties of Ti-sapphire grown by different methods in reducing medium

Kryvonosov, E.V.; Nizhankovskiy, S.V.; Lytvynov, L.A.; Bui, A.A. (Functional Materials, 2012)

Optical and laser properties of Ti-sapphire grown in reducing gaseous medium are studied. It is shown that HDSM-crystals have satisfactory functional characteristic and can be used for the making of wide-aperture laser ...
Peculiarities of optical and structure characteristics of sapphire single crystals grown in Ar + CO atmosphere

Dan’ko, A.Ya.; Tkachenko, V.F.; Sidelnikova, N.S.; Puzikov, V.M.; Nizhankovskiy, S.V. (Functional Materials, 2004)

Presented are the results of optical and X-ray structure investigations of sapphire crystals grown by the method of HOC in the protective (reducing) medium Ar+CO under a pressure of 10...800 torr. The dependence of the ...
