| This work reports the dependence of photoluminescence properties of LiNbO3 (LN) single crystals, on the Zn doping concentration. The samples were grown by Czochralski technique and were doped with zinc at concentration from 5 to 9 mol %. Structural and photoluminescence (PL) properties were studied by Raman, UV reflectance and fluorospectrometry, respectively. An extraordinary violet luminescence at 425 nm with excitation in UV region (380 nm) was observed. The emission peaks in PL spectra varied in amplitude and in wavelength position according to the level of concentration of Zn in the LN single crystals. It was found an optimal level concentration of Zn in the LN crystals studied in order to obtain a strong PL signal. The PL properties found in the LN crystals studied were related to the ratio of Li/Nb concentration. | |
