“…Due to these excellent characteristics, many researches are being concentrated in the growth and device fabrication of these family crystals. Though these crystals are grown by both hydrothermal and high temperature solution growth technique using self-flux (OSELEDCHIK et al;CHENG et al (1994);HAN et al;BOLT et al) and/or tungstate solvents (CHENG et al(1991)), the latter method has been followed by many workers due to its added advantages like faster growth rate and the absence of OH ions into the grown crystal lattices. It is well known that in tungstate and molybdate fluxes, which are less viscous, faster dissolution kinetics and low temperature solvents make crystal growth easy.…”
