Summary: | •Large Na2Mo2O7 crystals were grown by low-thermal-gradient Czochralski technique.•Na2Mo2O7 morphology and its dependence from growth direction were studied.•Three cleavage planes (0 1 0), (0 0 1) and (0 2 1) were detected.•Na2Mo2O7 photoluminescence, thermostimulated luminescence, Raman spectra were studied.
For the first time Na2Mo2O7 crystals were grown by Czochralski technique in low-thermal-gradient conditions (LTG Cz), which allowed obtaining crystals of record size (100 (D) × 45 (L) mm3) and optical quality. Influence of growth rate and seed direction on crystal morphology was studied, optimal growth conditions were determined. Three cleavage planes: (0 1 0), (0 0 1) and (0 2 1), were detected. Different characterizations of Na2Mo2O7 crystal samples, such as: transparency, photoluminescence, thermostimulated luminescence and Raman spectra were studied. |
