“…Many techniques have been studied to fabricate nanostructures, such as nanoholes and nanogrooves on the scale of several hundred nanometers or less, including: processing high aspect ratio nanoholes in SiO 2 substrates using femtosecond pulsed lasers [20][21][22]; fabrication of nanoholes, periodic nanostructures, and nanodot structures in metals using femto/picosecond pulsed lasers [23,24]; and drilling submicron holes in polymers using femtosecond pulsed lasers at extreme ultraviolet (XUV) wavelengths [25]. There are many reports on new nanostructure-processing methods and patterning that exceed the diffraction limit of laser light; however, to our knowledge, there have been no sufficient studies on polycrystalline zirconia for nanoholes, except for the formation of nanogrooves [26][27][28]. Therefore, in our previous study, we proposed a new method to fabricate nanoscale pores in YSZ.…”

Femtosecond pulsed laser irradiation was performed to investigate the feasibility and fundamental characteristics of embedding silver nanoparticles onto zirconia ceramic surfaces. By irradiating laser, nanopores were fabricated on the surface of the yttria-stabilized zirconia (YSZ) substrate, and silver nanoparticles were infiltrated and immobilized into the pores using a commercial nano-silver dispersion solution. Numerous nanopores embedded with silver nanoparticles were successfully obtained on the YSZ surface while keeping the grains’ shapes unchanged by controlling laser parameters. Optimizing laser fluence and scanning speed near the ablation threshold made it possible to remove only the excess dispersant that remained on the surface while keeping silver in the pores and without causing machining of the surface of the YSZ substrate. In addition, about 60% embedding in the nanopores was achieved. It was found that the shorter pulse width was suitable to avoid evaporating both dispersant and silver. Cross-sectional observation revealed that the silver nanoparticles were agglomerated to form clumps and were embedded without a gap at the bottom of the pores at a depth of about 600 nm. After laser irradiation, no significant laser-induced phase change was observed in the YSZ substrate, indicating that there was no in-process thermal damage to the bulk. These findings demonstrated the possibility of adding a metal nanoparticle to the zirconia surface by using only a laser process without damaging the properties of the base material during the process. New applications of zirconia, such as the generation of functional surfaces with antibacterial properties, are expected.

Control of exposed crystal facets in nanostructures is scientifically important, but technically challenging due to the inherent difficulty in manipulating surface energy of crystals. Here, laser‐induced periodic surface structures (LIPSS) induced by femtosecond laser is applied to produce periodic subwavelength 1D nanostructures with high index crystal facets on epitaxial CoFe2O4 surfaces, providing an efficient, maskless, cost‐effective “top‐down” method for nanostructure fabrication. Homogenous 1D LIPSSs (1D‐LIPSSs) with a period of 131 ± 15 nm and a depth of 90 ± 5 nm are obtained. The orientation of LIPSS nanostructures is finely controlled by tuning the polarization of fs laser beam, therefore flexibly producing 1D‐LIPSSs along various crystallographic orientations. Gas sensing performance evaluation shows that the fabrication of 1D‐LIPSSs on CoFe2O4 enlarges its surface area and contributes to enhanced gas sensing response. Compared to CoFe2O4 with LIPSSs faceted along {100} orientation, CoFe2O4 with LIPSSs faceted along high‐index {110} facets exhibits further improved gas sensing performance, suggesting the critical role of high‐index crystal facets in promoting surface reactivity and sensing sensitivity. The development of a laser‐based nanostructure fabrication route with high controllability of exposed crystal facets provides a novel solution for high‐density film‐based gas sensing applications.

Nanostructures of noble metal offer an exciting opportunity to tune photoluminescence (PL) in 2D materials, which has shown promise for applications in plasmonic devices. However, an efficient, designable, residue‐free nanofabrication method remains challenging. Herein, a one‐step ultrafast laser nanofabrication method is performed in fabrication of laser induced periodic surface structure (LIPSS) with continuously tunable periods over a wide range (from 439 to 2086 nm) on Au. The process of LIPSS imprinting is revealed at different time scales: periodical energy deposition within hundreds of femtoseconds, phase transition after 10 ps, and resolidification after 200 ps. Furthermore, the intensity and peak shift of PL in monolayer MoS2 (1L‐MoS2) can be tuned by LIPSS, 11‐fold enhancement resulting from nanoscale confinement of the incident laser and exciton‐trion localized interconversion emanating from hot electron transfer and tensile strain. The results are promising for 2D‐materials/metal heterostructures to applications in plasmonic devices and nanophotonic integrated circuits.
