Figure 4
Comparison of the crystal morphology between the OCP and control groups. OCP: the crystals were optically better in the OCP group than in the control group. Control: the crystals were optically better in the control group than in the OCP group. Comparable: the optical perfection of the crystals was comparable in the two groups. The results showed that more crystals grown in the OCPs exhibited better optical perfection than those grown in the control plates. The optical perfection was compared using the following criteria: First, the crystals were categorized into different groups and ranked as follows: single crystal > single crystal with cracks > twin crystal > needle cluster > quasi-crystal. If the crystals were in the same group, then they were compared according to their size: larger crystals were defined as more optically perfect. If the crystal sizes were similar (size difference was within 5%), they were optically comparable.
