Abstract

This work presents the synthesis and characterization of Homophase CdS and Heterophase Fe/CdS nanoparticles prepared by pulsed laser ablation (PLA) in water and methanol using nanosecond duration Nd:YAG laser. The morphology, the crystalline state, and the structure of the products were examined by performing SEM, XRD, and FTIR measurements, respectively. The results showed the transformation of the crystalline phase and changing the clustering size of CdS nanoparticles when performing PLA in methanol and water. Fe/CdS Heterojunctions were obtained in both liquids. The presence of Fe nanoparticle imposed another phase transformation and significantly improved the aggregation properties of the CdS nanoparticles.
