ResumoWe have successfully grown colorless and crack-free βII-Li3VO4 single crystals by the Czochralski method using a self-flux. To improve the quantity of crystals, we installed a heat reservoir in the growing furnace, used the melt composition as Li2CO3:V2O5=58:42 (Li/58) to avoid the unnecessary phase transition and set the growth temperature below 700°C to avoid the cracking. The physical properties of the crystals were studied by the powder X-ray diffraction, impedance/gain phase, differential thermal analysis (DTA), and UV–VIS transmittance spectroscopy measurements. We found that the physical properties of Li/58 crystals were almost identical to those of Li/70 crystals except the UV–VIS transmittance data.
