Abstract


Cadmium sulfide (CdS) nanoparticles plays a pivotal role in photovoltaics, sensors and detectors. The present work is on preparation of monodisperse CdS nanoparticles by using cadmium iodide and sodium sulfide as a precursor, where sodium hydroxide (NaOH) acts as a capping agent in methanol solvent. Synthesis of CdS nanoparticles was carried out with different molar concentrations of NaOH.The particle sizes were calculated from Bru’s equation by using UV-Visible absorption spectrum. The functional groups of the samples and morphology were studied by FTIR and HRTEM respectively.

Keywords
