Abstract :In the present work synthesis, structural and morphological analysis of ZnO nanowires with CdS layer core–shell heterostructure is reported. The sol-gel and hydrothermal method was used to synthesize the core shell hetrostructure. X-ray diffraction spectrum, field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), UV-Visible spectroscope were used to identify and analyze the structural properties, samples morphology and energy band gap of as prepared heterostructure. The crystallite size of ZnO has been obtained approximately 24 nm and that for CdS is approximately 20 nm. HR-TEM and FESEM images show that the CdS shell was deposited on ZnO nanowires and the thickness of core-shell structures was found to be in the range of 30 to 80 nm. UV-visible spectroscopy was used to examine the energy band gap revealing the fact that energy band gap reduces to 2.30 eV for present structure from 3.37eV for pure ZnO.
