This research synthesizes and characterizes cadmium and cobalt sulfide heterostructures, showing significant optical properties for electronics.

The aim is to synthesize and characterize CdS and CoS heterostructures for potential applications in optoelectronics.
Synthesized thin films using chemical bath deposition at 80°C for 1.5 hours.
Utilized cadmium acetate, cobalt acetate, thioacetamide, and EDTA as precursors.
Characterized films using X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and optical absorption spectroscopy.
CdS and CoS films exhibited direct band gaps of 2.4 eV and 1.6 eV, respectively.
Heterostructures showed dual band gaps of 2.4 eV (CdS) and 1.65 eV (CoS) for CdS/CoS.
XRD confirmed cubic structure for CdS, hexagonal for CoS, and mixed structure for CdS/CoS.
