CTAB capped CdS nanoparticles were prepared through hydro thermal method. Structural, chemical composition and optical properties were evaluated by different analytical techniques. Powder X-ray diffraction (XRD) analysis of the CTAB capped CdS nanoparticles reveals the formation of hexagonal structure and also confirms the crystalline nature of the particles with distinct lattice environment. In Fourier transform infrared spectroscopy (FTIR), the composition of the CTAB capped CdS nanoparticles have been confirmed. Optical transition show a blue shift due to the increase of band gap energy and it is attributed to the low defects and high crystallinity. Optical band gap of pure and CTAB capped CdS nanoparticles were found to be 2.27 eV and 2.35 eV. The optical studies indicate that CdS nanoparticles with CTAB can be suitable for optoelectronic devices and photovoltaic applications.
