“…Атом рутения может существовать в трех валентных состояниях Ru 3+ , Ru 4+ и Ru 5+ [23]. Таким образом, в процессе легирования исследуемых кристаллов вероят-ным является искажение кислородных тетраэдров струк-туры BTO с образованием кислородных вакансий, спо-собных захватить электрон в соответствии с условием компенсации.…”

Изучена проводимость кристаллов Bi12TiO20:Ru на переменном токе в интервале частот 102...106 Hz и температур 293...773 K. Анализ экспериментальных данных проводится в рамках модели коррелированных барьерных прыжков. В исследуемом материале потенциальные барьеры обусловлены наличием блочной структуры, дефектов кристаллической решетки, а также присутствием примеси рутения. В легированных монокристаллах титаната висмута определены микропараметры, характеризующие процесс переноса заряда. Работа выполнена при финансовой поддержке Министерства образования и науки РФ в рамках базовой части государственного задания 24/14-ПГЗ. DOI: 10.21883/FTT.2017.06.44476.363

“…Furthermore, by selecting the photorefractive substrate sensitivity, the operation interval of the proposed hybrid devices can be easily adjusted. Moreover, doping sillenites with transition metal elements significantly improve their sensitivity and response time at nearinfrared spectral range [17][18][19][20][21][22].…”

The chapter reviews recent progress of two-wave mixing in a novel organic-inorganic hybrid structures that combine essential properties as large anisotropy and strong birefringence, typical for organics with the excellent photosensitivity and photoconductivity of inorganics into single, compact devices. Depending on the designed assembly and operation principle, the proposed structures can record dynamic holographic gratings at Raman-Nath or Bragg regimes of diffraction, respectively. When the two beams interact in a structure based on a photoconductive material and birefringent layer (usually liquid crystal), the beam coupling with high amplification values occur in a liquid crystal layer, however, the fringe period of recorded holograms is limited to few μm scale. In contrast, when the two beams interact in a structure based on a photorefractive material and birefringent layer, the beam-coupling occurs in both composites, due to the surface activated photorefractive effect. The prime significance of the later structure is the ability to act as a holographic grating at Bragg regime allowing sub-micron spatial resolution. Moreover they are easy and simple to fabricate where the processes are all optically controlled. The above examples open scenarios to design new devices that meet the latest requirements of 3D display technologies and optical information processing.

“…The photochromic effects caused by the Ru doping in the NLO crystals such as Bi 12 SiO 20 , Bi 12 TiO 20 , Bi 4 Ge 3 O 12 and Sr 0.61 Ba 0.39 Nb 2 O 6 have been observed and reported [6][7][8][9]11]. The photochromism of Ru:LiNbO 3 was first reported by Fujimura et al [13], and the three-valence state of Ru ion was considered as a possible origin of the photochromism.…”

“…The doping of Ru ions has been proven to be useful to improve the photorefractive properties of many nonlinear optical (NLO) crystals such as Bi 12 SiO 20 [6], Bi 12 TiO 20 [7,8], Bi 4 Ge 3 O 12 [9], BaTiO 3 [10], Sr 0.61 Ba 0.39 Nb 2 O 6 [11] and KNbO 3 [12]. Recently, nonvolatile holographic recording at a wavelength of 632.8 nm in Ru: LiNbO 3 crystals has been investigated [13].…”
