  • Molybdenum disulfide (MoS 2 ) has been extensively investigated as the key material for post-silicon electronics, optoelectronics (flexible devices), Li-ion batteries, solar cells, etc. In the work presented, MoS 2 nanoparticles (NPs) were obtained via the laser (Nd:YAG, λ = 1064 nm) ablation of a bulk MoS 2 in ethylene glycol solution, as a function of the laser fluence, for the first time. The properties of the product were characterized using UV–vis, TEM, SAED, SEM with EDX, XRD, FT-IR, and Raman spectroscopy. The results showed that the synthesized MoS 2 NPs have a hexagonal crystalline structure with diameters of 4–160 nm. In addition, most of them had a rounded shape whose λ max varied from 212.5 to 216.5 nm depending on the laser fluence. By increasing the laser fluence, the average size of these particles increased from 10 to 18 nm. The shape and size of MoS 2 NPs have a significant role in the fields of lubrication, catalysis, electrocatalysis, etc. Laser ablation method is a clean, simple, and reproducible way to produce nanostructures with special properties.
