Hydrothermally grown CdS-embedded graphene oxide nanocomposites with enhanced optical properties

Abstract

Nanocomposites based on graphene oxide have shown significant potential in various applications, including solar devices. In this work, hydrothermally synthesised cadmium sulfide-embedded graphene oxide (GO-CdS) nanocomposites have been reported. The resulting powder is black and was filtered and washed with distilled water. The samples were then characterised by X-ray diffraction, FTIR, 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 (CdS) in the graphene oxide increases, the size of the nanocomposites also increases. FTIR analysis confirmed the formation of GO-CdS nanocomposites. Furthermore, the samples exhibited excellent photoluminescence, which makes these composites highly suitable for optoelectronic applications.
