Growth of beta(II)-Li3VO4 single crystals by the heater-in-zone zone-melting method using a traveling solvent of LiVO3
Low-form (B-II-) Li-3 VO4 single crystals have successfully been grown by the heater-in-zone zone-melting method using a traveling solvent of LiVO3. The as-grown crystals are transparent and have no cracks or bubble inclusions. To prevent the crystals from cracking, the temperature of the heater is set to below 700 degrees C. The growth rate must be less than 0.25 mm/h and the crystal rotation rate more than 30 rpm in order to eliminate bubble formation. The formation of low-angle grain boundaries is effectively suppressed by growing the crystals along the [0 0 1] direction. The emission of green light from the as-grown beta(II)-Li-3 VO4 single crystal is observed by irradiation with a Nd : YAG laser.
