Characterization of CdS@Cu Core-Shell Nanostructures Synthesized by Laser Ablation Method

Abstract

Core-shell nanoparticles, known for their structural, optical, and electrical properties, being investigated for optoelectronic and medicinal applications. CdS and Cu nanoparticles are synthesized via laser ablation in a liquid media, concentrating on the core-shell technique's effect on laser ablation and CdS@Cu nanoparticle characteristics. Nd:YAG laser pulses at 1064 nm and 480 mJ ablate CdS and Cu nanoparticles in water, with CdS being the core and Cu the shell. Ablation improves crystallinity and CdS production, according to structural studies. The core or shell morphology reduces particle aggregation. UV-VIS spectroscopy, XRD, FESEM, and AFM verify unique features. The CdS@Cu phase is cubic according to XRD. FE-SEM shows 34.2-90.7 nm spherical particle clusters, and AFM confirms synthesis.
