Laser-assisted fabrication and modification of copper and zinc oxide nanostructures in liquids for photovoltaic applications

Biodegradable Polymer Nanosheets Incorporated with Zn-Containing Nanoparticles for Biomedical Applications

“…As was revealed by XPS analysis (see Fig. 5), NPs prepared by LAL of Zn in chloroform, along with dominating Zn-Cl species, also contained some fraction of surface Zn-OH, metallic Zn, and traces of C-Cl bonds [15,17,18,23,29,36]. Therefore, in contrast to NPs of commercial ZnCl2 salt, for simplicity in this study we denoted such LAL-generated materials as Zn-Cl NPs.…”

“…In this study, we prepared Zn-containing NPs by LAL of Zn in chloroform or water, aiming at obtaining ZnCl2 and ZnO NPs, respectively. While laser ablation of metallic Zn in water is known to result in zinc oxide or/and hydroxide NPs [15,17,18,23,26,28,29,31], LAL processing of Zn plate in chloroform was not reported before. Chloroform was chosen as reaction medium for LAL for two reasons: (i) because ZnCl2 based NPs were expected, and (ii) because chloroform was then used as solvent for spin-coating of PLLA NSs without the necessary to centrifuge produced NPs and redisperse them in chloroform.…”

“…1), sulfides, carbides, etc. [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. In this approach, laser beam is typically focused on a solid target, its pulses ablating the target and producing various nanostructures whose morphology, size and chemistry depend on the laser pulse parameters and liquid medium [14][15][16][18][19][20][21]25,29,30].…”

Laser-Based Synthesis of TiO2-Pt Photocatalysts for Hydrogen Generation

“…It is noteworthy that pulsed laser ablation in liquid (PLAL) has been increasingly used in recent years to produce catalysts for various purposes [ 41 , 42 , 43 ], including for the photocatalytic hydrogen generation [ 44 ]. Extreme nonequilibrium conditions in laser synthesis (pressure, temperature, ionization, etc.)…”

Hybrid Au-Si microspheres produced by laser ablation in liquid (LAL) for temperature-feedback optical nano-sensing and anti-counterfeit labeling

“…This provides a pathway for the preparation of nanomaterials with a wide range of morphology, structure and composition (including meta-stable and non-equilibrium phases). Laser irradiation of LAL-generated dispersions can further expand the method functionality, allowing for highperformance preparation of diverse hybrid nanomaterials for photovoltaics 17,18 , photothermal conversion 19,20 , catalysis [21][22][23] , nonlinear optics 24 , sensing [25][26][27][28] and medi-cal applications 29,30 . Gold, the most chemically stable plasmon-active metal, and silicon, an earth-abundant semiconductor widely applied for all-dielectric metasurface design, present an intriguing combination, in which the advantages of plasmonic and nanophotonic concepts can be merged within unified nanostructures.…”
