Dipole relaxation, dielectric and electric properties of PbWO₄ crystals

Shevchuk, V.N.; Kayun, I.V. (Functional Materials, 2005)

Experimental dependences of permittivity for undoped PbWO₄ single crystals at 1 kHz frequency in 290-550 К temperature range are considered. The ε(Т) curve runs under heating and cooling are different. The ε(Т) function ...
Electrical and deilectric properties of CdWO₄ crystals

Shevchuk, V.N.; Kayun, I.V. (Functional Materials, 2006)

Electrophysical investigations of CdWO₄ crystals have been carried out by thermostimulated polarization and thermoelectret state depolarization in interrelation with temperature dependences 290-550 K of DC conductivity and ...
Luminescence of gallium-containing complex oxide crystal

Shevchuk, V.N. (Functional Materials, 2005)

Luminescence spectra of garnet Nd₃Ga₅О₁₂ and of acentric Ca-gallogermanate Сa₃Ga₂Ge₄О₁₄:Nd³⁺ crystals under pulsed X-ray excitation (-1.5 ns) in 200-500 nm range are considered. The luminescence measurements carried out ...

Shevchuk, V.N.; Usatenko, Yu.N.; Demchenko, P.Yu.; Antonyak, O.T.; Serkiz, R.Ya. (Functional Materials, 2011)
Obtaining and observation of micro- and nano-size V₂O₅ structures

Shevchuk, V.N.; Usatenko, Yu.N.; Demchenko, P.Yu.; Antonyak, O.T.; Serkiz, R.Ya. (Functional Materials, 2010)
Structure features and paramagnetic centres in oxide nanopowders

Shevchuk, V.N.; Popovych, D.I.; Usatenko, Yu.N.; Demchenko, P.Yu.; Serkiz, R.Ya. (Functional Materials, 2009)

Nanopowders ZnO, SiO₂, SiO₂/10 % V₂O₅ obtained by sol-gel technology were investigated by electron paramagnetic resonance (EPR) method at temperature of liquid nitrogen. The structures of the samples are analyzed by X-ray ...
