Flux growth and morphology analysis of Na3VO2B6O11 crystals

Colorless and transparent Na3VO2B6O11 (NVB) crystal has been grown by the top seeded solution growth method using NaVO3 as the flux at cooling rates of 0.8–1.5 °C/day, in the temperature range 610–650 °C. A well-developed morphology of the crystals was observed and analyzed. The grown crystals were characterized by powder X-ray diffraction (PXRD), infrared spectroscopy and second harmonic generation (SHG) test.
