| xx single crystals were grown by the optical floating zone method. The as-grown samples were dark brown in color and had a size of §¶ 4-6 mm ¡Á L 87 mm£¬with the largest crystal domain of §¶ 5 mm¡Á L 32 mm. After being annealed, the color of the sample faded to light brownish. The powder X-ray diffraction analysis showed that the crystals had a columbite-type MgNb2O6 structure. The crystal grew along the c-axis direction and the cleavage plane could be indexed to b-axis direction. Transmission polarized-light microscopy measurements displayed that the crystal was free of low angle grain boundaries and inclusions. Raman scattering was also used to characterize the crystals and gave the change of x-O band annealed and non-annealed. The photoluminescence spectra exhibited a broad and strong blue emission band centered at 435 nm. |
