Structure of LiNbO3:Zn crystals was shown to be more ordered in concentration range ~3,95 ÷ 4,54 mol. % ZnO . Rise of dopant concentration to 5,84 mol. % leads to sharp increase of 876 cm^(-1) Raman band. This band is connected with changes in B-O-B

Using photoinduced light scattering parameters at wavelengths of 476.5, 488.0, 514.5, and 532.0 nm, we have assessed the photovoltaic and diffusion field strengths in nominally undoped and doped lithium niobate crystals. The results demonstrate that

We have investigated Raman spectra of congruent and stoichiometric LiNbO3 crystals in the temperature range 100–450 K. Slope gradient is greater for the temperature dependence of band width associated with Nb5+ ions vibrations than that associated

LiNbO3:ZnO (3.43–5.84 mol %) crystals have been studied using Raman spectroscopy and fullprofile analysis of X-ray diffraction data. The results demonstrate that, at ZnO concentrations above 3.95 mol %, their structure is free of NbLi basic defects

We have studied the detailed structure and mechanical properties of the Nb2O5 and Ta2O5 pentoxides after ultrarapid quenching in comparison with the properties of Nb2O5 and Ta2O5 ceramics prepared by a conventional ceramic processing technique and us

Photoinduced light scattering (PILS) in nominally pure stoichiometric and congruent lithium niobate single crystals (LiNbO3), and ones doped with B³⁺, Cu²⁺, Zn²⁺, Mg²⁺, Gd³⁺, Y³⁺, Er³⁺ cations was studied. All crystals have a rel
