Microwave assisted synthesis of CdS nanoparticles for structural and optical Characterization

Shiv Kumar Choubey, K.P.Tiwary

The nanoparticles of CdS were successfully synthesized by Microwave assisted irradiation method. CdS materials can be used for the fabrication of solar cells, nonlinear optical materials, optoelectronic and electronic devices. X-ray diffraction (XRD) and scanning electron microscopy (SEM) technique were used for structural and morphological characterization of nanoparticles of CdS. XRD characterization of nanoparticles were taken which verify the crystalline form. The average size of the nanocrystallites were measured by Debye-Scherrer formula as per the XRD spectrum and the particle size lies in the range 4 - 7 nm. The optical characterization of the nanoparticles of CdS were taken by UV-Visible absorption spectra and the optical bandgap of as synthesized CdS nanoparticles were found to be 3.8 eV.
