  The technology to grow single crystals of the required shape directly from a
melt has been researched extensively and developed in various industries and
research fields. In this study, a micro-pulling-down method and a Mo crucible
were applied to the shape-controlled crystal growth of Y$_3$Al$_5$O$_{12}$:Ce
(YAG:Ce). Three types of Mo crucibles with different die shapes were developed.
Stable crystal growth in the same shape as the die was achieved, and
scintillation properties that are comparable with those of the previously
reported YAG:Ce were obtained.
