| Lithium niobate LiNbO3 (LNO) is a photorefractive nonlinear optical material, which exhibits very strong electro-optic behavour and photoconductive effects connected to high optical non-linearity. In this work, we evaluate by Raman and reflectance difusse Uv-vis spectroscopies, the influence of Zn in LNO single crystals. The samples were prepared by Czochralski technique and were doped with zinc at concentration from 5 to 9 mol %. The evolution of the half-widths of E(TO) and A1(TO) Raman bands indicate no variation in lattice vibrations with slight changes in the peak width and intensity. On the other hand, the evolution of ratio Li/Nb concentration was determined by Raman and UV reflectance diffuse spectroscopies, respectively. The evolution of indirect band gap energy of Zn-doped LNO shows that energy values in a range of 3.9 to 4.0 are larger than expected to undoped lithium niobate | |
