Growth of an 8-hydroxyquinoline single crystal by a modified Czochralski growth technique, and crystal characterization

Author affiliations

Abstract

A novel modified Czochralski crystal growth technique for low temperature was designed with a closed chamber which allowed for variations in the environment. A large sized single crystal of 8-hydroxyquinoline with diameter 1.2 cm and length 7.4 cm was successfully grown in an argon atmosphere. Structural parameters were determined by the powder X-ray diffraction method. The functional groups were confirmed by Fourier transform infrared spectroscopy. Thermal transitions at various temperatures were measured by thermogravimetric/differential thermal analyses. The dielectric properties of the grown crystal were studied with variations of temperature and frequency. The grown crystals were found to be piezoelectric as confirmed by the d33 coefficient of 5 pC Nāˆ’1. A Vickers microhardness study revealed that the grown crystal belongs to the soft type single crystals with a Meyer's index (n) of 1.98.
