Unidirectional growth, optical and dielectrical behavior of Nicotinium p-Toluenesulfonate crystal for optoelectronic applications

Typical PXRD pattern and their peak positions clearly evidences that the grown crystals are NPT with strong (001) orientation. The corresponding (001) plane intensity is increased significantly for NPT crystal grown by UGCT when compare with NPT crystal grown by SEGT. Noticeably, the peak intensities of other orientations diminished for NPT crystal grown by UGCT, further support the unidirectional growth of NPT via UCGT with (001) specific orientation.
