During the growth process of organic crystals, it is easy to induce thermal defects and impurities when using the conventional Bridgman technique. In the present study, a specially designed double-wall ampoule was used to solve this problem. High-quality p-terphenyl single crystals were successfully grown by the vertical Bridgman method with the improved ampoule. Powder X-ray diffraction analyses were performed to evaluate the crystallinity of the grown single crystals. Fluorescence spectrum studies show an enhancement of fluorescence properties due to the improvement in crystalline perfection.
