Growth and characterization of propyl-para-hydroxybenzoate single crystals

摘要

Single crystals of propyl-p-hydroxybenzoate have been grown by slow evaporation solution technique. The structure of the compound was confirmed by FT-IR, FT-Raman spectroscopy and single crystal X-ray diffraction studies. The crystalline perfection of the grown single crystals has been analysed by high resolution X-ray diffraction measurements. Optical properties of the grown single crystals were studied by UV-Vis NIR spectrum. The luminescence behaviour of the single crystal has been analysed by photoluminescence analysis and found maximum luminescence in the lower wavelength region. A simple interferometric technique was used for measuring birefringence of the crystal. The laser damage threshold of the crystal is 1.3 GW/cm(2). The mechanical strength of the grown crystal is measured using Vickers microhardness tester. The dielectric properties have been investigated.
