Abstract
The present work reported the Zn doped CdS nanostructures synthesized via using co-precipitation method from cadmium and sulphide particle arrangements with no ligands at different temperature arrangement and amalgamation time. The as synthesized CdS nanostructures were characterized by XRD, SEM, PL, Raman, FTIR and UV–vis spectroscopy to investigate the structural, morphological, and optical properties. XRD analysis revealed that all the samples were acknowledged the cubic crystal structure and crystallite size is found in 3–9 nm range. SEM analysis exhibits that synthesized material is in nano size range. PL, Raman and FTIR analysis also revealed that the inorganic component in all the synthesized samples is a CdS phase with a cubic crystal structure. An enhancement in optical band gap is observed with increasing Zn doping concentration in CdS nanostructures. The investigation revealed that Zn doping plays a significant role to tuning structural and optical properties of CdS nanostructures, which influence the particle size, band gap and morphology. Therefore, the synthesized CdS nanostructures at different doping concentration of Zn can be used as a window layer for solar cell applications and optoelectronic devices.
