摘要：
The ethyl 4-hydroxybenzoate single crystals were grown by modified vertical Bridgman technique using two different temperature profiles. The grown ethyl 4-hydroxybenzoate crystals were confirmed by single crystal X-ray diffraction studies. Fourier Transform Infrared spectroscopy (FTIR) studies is used to identify the functional groups of the grown ethyl 4-hydroxybenzoate. The thermal behaviour of the ethyl 4-hydroxybenzoate was analyzed by the thermogravimetric analysis (TGA), differential thermal analysis (DTA) and differential scanning calorimetric (DSC) analysis. The grown crystals were subjected to UV-Vis-NIR, fluorescence, photoconductivity, Vickers microhardness, dielectric studies and these results were compared. (C) 2017 Published by Elsevier Ltd.
