摘要：This manuscript presents Cu/CdS composite thin films fabricated on glass substrate via spin coating method. The doping of Cu in CdS has been done within the fraction of x= 0.1, 0.3, 0.5 wt%. The structural, optical, electrical and morphological characterization of CdS and Cu doped CdS were characterized by X-ray diffractometer (XRD), UVVis spectrometer, Keithley electrometer, FT-IR, Photoluminescence (PL) and Scanning electron microscopy (SEM). XRD spectra confirms cubic phase with particle size distribution of 38-48 nm. The optical direct band gap values have been found in between 2.41 to 1.71 eV for Cu doped CdS composite thin films. Fourier transforms infrared spectrometer (FT-IR) used for bonding analysis and identification of functional groups. The photoluminescence (PL) spectrum emitted a strong peak near band edge emission at approximately 430 nm, attributes better optical quality. A better control in the doping process improves tuning of the band gap, electrical nature for energy applications.
