Abstract    


  

Single crystals of copper sulfate pentahydrate (CSP) were grown up to (21.6×19.38×3 mm3), (14.5×34.11×42.3 mm3) and (42.4×27.36×7.5 mm3) from aqueous solution by slow evaporation technique at room temperature using double distilled water, H2SO4 acid and magnetic water as solvents respectively. Structure analysis of grown crystals was carried out by X-ray diffraction technique. The study of the vibrational modes for the grown crystals was conducted by FTIR spectroscopy. It is observed that the H2SO4 acid led to the disappearance of Cu+2 metal ion (Cu-O-H) mode in crystal, while the magnetic water led to appearance of it with less intensity compared by appearing in the crystals grown using distilled water. The UV-Visible result shows that the crystals have cut-off at 280 nm, 292 nm and 287 nm, with optical energy gap (4.23 eV, 4 eV and 4.09 eV) for crystals grown using distilled water, diluted acid and magnetic water as a solvent respectively.
