NdAl3(BO3)(4) single crystals were grown by the flux method and the TS
SG technique using a K2O/3MoO(3)/B2O3/0.5Nd(2)O(3)/KF flux system. Lig
ht-violet clear crystals could be obtained. The effects of fluoride on
the growth of NAB crystals were investigated. As the content of KF wa
s gradually increased, the growth form of NAB was changed from the equ
ant to the columnar and the primary crystalline region of NAB was shri
nked. At the ratio of KF/K2O = 0.75, NAB crystals could not be grown.
