Summary: The application of pulsed laser ablation technique for generating cerium-doped garnet nanoparticles in liquids is investigated. The morphological and optical properties of the obtained nanoparticles are demonstrated. The influence of single crystals of Gd3Al2.4Ga2.6O12:Ce3+, Lu3Al5O12:Ce3+, and Y3Al1.25Ga3.75O12:Ce3+ as well as the parameters of liquid media on the generation of garnet nanoparticles are experimentally studied using TEM and UV-Vis spectroscopy methods. The study reveals the relationship between the size, shape, and internal structure of the nanoparticles and the external laser ablation conditions and laser melting processes of NPs in the colloidal solutions. This work provides important information for the utilization of the generated nanoparticles as building blocks for structures with predetermined optical properties.

Summary: The study investigates the stability evolution of silver nanoparticles in colloid, showing that uncapped Ag NPs exhibit good dispersion stability but are easily disrupted by oscillation treatment, leading to the formation of one-dimensional nanochains. Surface capped Ag NPs with typical cationic and anionic surfactants display better dispersion and structure stability compared to uncapped Ag NPs, with CTAC capped Ag NPs showing superior chemical stability.

Summary: Cu-doped ZnS nanoparticles were successfully prepared using pulsed laser ablation in a liquid medium, with X-ray diffraction confirming formation of wurtzite ZnS structures and photoluminescence revealing additional green emission due to the presence of Cu2+. The doped nanoparticles showed more efficient photocatalytic behavior compared to undoped ones, believed to be attributed to enhanced light absorption into the visible region or carriers based on the Cu2+ state.

Summary: This study investigates the behavior of laser-induced cavitation bubbles under the influence of an external electric field. The results show that the maximum radii of the cavitation bubbles increase in response to an increasing electric field, with a more pronounced effect in the presence of acetone medium and a decreasing effect in ethanol and water media due to their varying electrical conductivity.

Summary: The rational combination of plasmonic and all-dielectric concepts within hybrid nanomaterials provides a promising route toward devices with ultimate performance and extended modalities. Fabricated hybrids with amorphous TiO2 nanospheres decorated and doped with Au nanoclusters demonstrate remarkable light-absorbing properties in the visible and near-IR spectral range, and were utilized to demonstrate applications such as a catalytically passive SERS biosensor and a solar steam generator.

Summary: An improved method for the production of luminescent carbon nanoparticles is proposed, which utilizes two-stage laser ablation in water to produce photoluminescent carbon structures. The use of urea as a reagent results in luminescence properties similar to those obtained with other more hazardous amine-based reagents. The influence of synthesis approach and process parameters on the structural and luminescent properties of nanoparticles is also explored.

Summary: The study on laser-based synthesis of InOx/ZrO2 catalysts with different particle sizes and loadings demonstrates potential, while also revealing that the preparation methods under different laser conditions can affect the morphology and activity of the catalysts. Results show that catalysts prepared under different laser conditions perform equally well as their wet-chemical prepared counterparts for methanol synthesis, suggesting the potential of in situ fragmentation for independent studies of size and composition with controllable structural modifications.

Summary: Iron nitride nanostructures were successfully synthesized using Nd:YAG laser in liquid nitrogen, forming single-phase alpha ''-Fe16N2, zeta-Fe2N, and epsilon-Fe3N nanostructures or a mixture of them. Varying the laser fluence allowed for obtaining different phases, and specific laser frequencies were found to be effective in producing complex iron nitride phases.

Summary: In this study, properties of zinc oxide (ZnO) were modified by creating Ag/Au-ZnO nanohybrids using pulsed laser ablation and irradiation in liquid. The hybrid nanomaterials showed optical absorption peaks of Ag/Au and changes in morphology from non-uniform to spherical. Higher ablation duration of bimetallic nanoparticles led to improved photocatalytic performance in visible-light. Overall, laser ablation and irradiation in liquid technique proved effective for green synthesis of plasmonic hybrid nanomaterials.

Summary: This study investigated the dynamics of laser-induced cavitation bubbles (LICBs) during pulsed laser ablation (PLA) of a nickel target in different solvents. It was found that the lifetime of LICBs depended on the liquid environment and strongly defined the phases of the Ni nanoparticles (NPs) formed. The prepared Ni NPs showed enhanced sensitivity and electrochemical performance, with the fcc/hcp Ni structure displaying the best performance.

Summary: This study focused on the generation of bimetallic oxide nanoparticles using a reaction-sintering method and laser ablation in liquids. The results showed successful production of nanoparticles without a core-shell morphology, influenced by the properties of metallic oxide ceramics and the liquid used. The research lays the groundwork for the creation of well-defined bimetallic nanoparticles with potential X-ray and magnetic absorption properties for multimodal imaging applications.
