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 Y3Al5O12: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…

Growth of Optical Crystals by the Micro-Pulling-Down Method
The micro-pulling-down technique is a crystal growth method that has been mostly developed since 1992. The general scheme of the growth system is relatively simple: the melt (oxide, fluoride, metal)
Multiple shaped-crystal growth of oxide scintillators using Mo crucible and die by the edge defined film fed growth method
Abstract Edge defined Film Fed Growth (EFG) method with molybdenum (Mo) crucible and die was studied for the growth of several oxide-based single crystals. At first, reactivity between the molybdenum
Crystal growth of Ce: PrF3 by micro-pulling-down method
Abstract Micro-pulling-down (μ-PD) growth apparatus was modified for fluoride crystals. PrF3 was grown with various concentrations of Ce3+ from 0–100%. The crystals were transparent and colorless
