The remarkable enhancement of the crystalline perfection of benzophenone (BP) crystals induced by liquid crystal (LC) doping has been investigated, and has in turn led to better optical properties. High-resolution X-ray diffractometry demonstrates that the structural grain boundaries present in pure crystals can be eliminated when the crystal is grown with LC doping. Thus, the high alignment capability of LCs has for the first time been utilized to enhance the quality of BP bulk single crystals. The LC-doped crystal exhibits higher optical transparency over its entire transparent region. The optical polarizing behaviour of the doped BP crystal is also improved.
