Colloidal synthesis of MoS2 NPs by nanosecond laser ablation of a bulk MoS2 target in ethylene glycol solution

Graphene/molybdenum disulfide nanocomposites: characterization and optoelectronic application

“…MoS2 NPs were generated using the laser ablation technique (Nd:YAG=1064 nm) in the polymer ethylene glycol solution as a function of laser fluence, according to Moniri and Hantehzadeh 28 . The resulting NPs are hexagonal crystals with diameters ranging from 4 to 160 nm, according to the findings.…”

PEGylated MoSe2 Nanomaterials with Limited Oxidation via Femtosecond Laser Ablation for Photothermal Therapy

“…31 The nanomaterials are usually stable in the ablated liquid because of surface-attached radicals such as hydroxyl groups when laser ablated in water, ethanol, and ethylene glycol. 24,27 The hydroxyl groups result in a negatively charged surface that prevents aggregation and sedimentation. 27 Additionally, laser-synthesized nanomaterials can be surface functionalized with polymers in situ when target materials and the polymers together.…”

Tsuji et al prepared silver nanoparticles surface functionalized with polyvinylpyrrolidone (PVP) by laser ablation of a silver plate in aqueous PVP solutions.…”

“…Recently, pulsed laser ablation in liquid (PLAL) was proven to be an efficient, simple, and green method to prepare TMDC nanomaterials including quantum dots and spherical nanoparticles. − PLAL involves irradiating femtosecond-laser or nanosecond-laser beams on bulk targets or powders in various solvents. The nanomaterials are usually fragmented from the ablated materials via photothermal mechanisms such as spallation, thermodynamic equilibrium melting, and vaporization and explosive boiling or direct, intense laser electric field–matter interactions such as Coulomb explosion and photoexfoliation, depending on the intensity and the pulse duration of the laser beam .…”
