for use in conductors, semiconductors, and insulators. [5] Electronic properties are indeed closely linked to the nature of the metal and conditions of fabrication, which determine the structure of the final material at the atomic scale. These properties can be modified by doping with different metals, by adjusting the metal to oxygen stoichiometry or by generating an amorphous or crystal phase. [6][7][8][9] Today, integration of MOs as thin films, micropatterns or nanopatterns by convenient and simple means remains a major challenge for the fabrication of electronic and optoelectronic devices. MOs are commonly deposited as thin films by sputtering. Though the sputtered MOs usually exhibit better electrical properties due to the accurate control of the composition and defect concentration at the atomic scale, solution-based processes have gained much attention during the last years due to their simplicity, cost effectiveness, vacuum-free processes, and high versatility.In solution-based processes, thermal annealing is required to eliminate the solvent and organic ligands that are complexed on metal ions and to obtain material and phase compositions with suitable properties. This step is typically conducted at temperatures ranging from 300 to 1000 °C. Thus, such a fabrication strategy can be difficult to apply in the case of multistep integration processes involving different materials.In this context, laser processing of MOs presents many advantages due to the control of the laser-matter interaction in space and time. [9] Laser curing allows a fast treatment that can be confined to a limited volume by focusing the laser beam. Such a laserinduced effect leads to a much lower energy consumption with respect to that of thermal annealing. For example, a pulsed laser in the ultraviolet (UV) or near-infrared (NIR) range has been successfully used for the crystal growth of amorphous MO films [10,11] or the hydrothermal growth of MO nanostructures. [12,13] Recently, laser processing has also been introduced for the direct writing of MO microstructures. For this purpose, UV or deep-UV (DUV) wavelengths are usually used. At the molecular scale, the patterning proceeds according to the photodecomposition of the metal precursors complexed by organic molecules. Patterning can be obtained at room temperature down to the nanoscale using direct laser writing (DLW), but usually, a thermal post-treatment is needed to obtain an MO with suitable Metal oxides are an important class of materials for optoelectronic applications. In this context, developing simple and versatile processes for integrating these materials at the microscale and nanoscale has become increasingly important. One of the major remaining challenges is to control the microstructuration and electro-optical properties in a single step. It is shown here that near-infrared femtosecond laser irradiation can be successfully used to prepare amorphous or crystallized TiO 2 microstructures in a single step using a direct laser writing (DLW) approach from a TiO 2 precursor ...

Laser‐Assisted Doping and Architecture Engineering of Fe₃O₄ Nanoparticles for Highly Enhanced Oxygen Evolution Reaction

The design and synthesis of cost‐effective and highperformance oxygen evolution reaction (OER) electrocatalysts for water splitting based on earth‐abundant elements is urgent but challenging. A synergistic doping and architecture engineering strategy by nanosecond laser ablation is used to generate a unique kind of highly disordered Ni‐doped Fe3O4 nanoparticle clusters. Ni dopant and increased oxygen vacancies are simultaneously incorporated into Fe3O4 frameworks and thereby modulate the electronic configuration for an optimal binding affinity towards OER intermediates. Nanoparticles with average size of around 5 nm assemble randomly during laser ablation and construct a fluffy and porous architecture, which not only optimizes the number of exposed active sites but also accelerates mass transfer. Consequently, Ni‐doped Fe3O4 clusters are revealed as a superior OER catalyst with a small overpotential of 272 mV at 10 mA cm−2 and a small Tafel slope of 39.4 mV dec−1, surpassing almost all spinel Fe‐based OER catalysts. This work provides a new strategy to fabricate advanced cation‐doped metal oxide nanostructures for related energy applications.

“…MONS is an important class of materials because they can be custom‐designed to produce insulating, semiconducting, or even conducting properties by controlling the basic structure of the M‐O‐M network . MONS are highly promising for various applications including photoelectric energy generators, sensing devices, optoelectronic, spintronic, and electronic devices . Current synthesis methods of MONS include gas‐phase techniques such as sputtering, laser deposition, atomic layer deposition (ALD), and thermal deposition.…”
