Hydrothermally grown optically enhanced CdS-GO nanocomposites Available to Purchase

Nanocomposites based on graphene oxide have shown significant potential in various applications, including solar devices. In this paper, hydrothermally synthesized cadmium sulfide (CdS)-embedded graphene oxide (GO–CdS) nanocomposites were reported. The resulting powder was black and was filtered and washed with distilled water. The samples were then characterized by X-ray diffraction, Fourier transform infrared (FTIR) spectroscopy, optical transmission and photoluminescence studies. The samples demonstrated a polycrystalline phase with a rutile structure and high luminescence peaks. As the amount of cadmium sulfide in the graphene oxide increased, the particle size of the nanocomposites also increased. FTIR analysis confirmed the formation of GO–CdS nanocomposites. Furthermore, the samples exhibited excellent photoluminescence, which made these composites highly suitable for optoelectronic applications.
