A Facile Synthesis of Nanophase Cadmium Sulfide Semiconductor

Sanjoo Yadav, Ashok Kumar

Abstract: Physical properties of materials are independent of the sizes when the sample is bulk, but start depending on the particle sizes of nanometer (nm). Especially, binary semiconductors show controllable multifunctionality in a single system, like magnetism and opto-transparency in semiconductors suited for spin-based electronics. Cadmium sulfide and stannic oxide nanoparticles are such perspective materials. In this work, we report a facile green synthesis of undoped nanophase CdS, characterized by X-ray diffraction, SEM, and uv-vis spectroscopy. It crystalizes in the cubic unit cell of edge a=b=c= 0.5796 nm with a microstrain of -0.022 in a mean particle size of about 2 nm as observed by Williamson-Hall plots. The uv-vis absorptions data generate Tauc Plots giving the optical band gaps of 2.64eV in the reference. Its microstrain and defects may have magnetic consequences.
