“…Among the various plating techniques, laser-assisted metallization is considered a promising approach for metallization on both common surfaces, such as polyimide, and challenging surfaces, such as PTFE. When compared with other microfabrication techniques, such as photolithography, , inkjet printing, and screen printing, DLW offers several advantages, including high spatial resolution, environmental friendliness, fast processing rate, and the capability to metallize a wide range of materials, such as glass, , polymers, , paper, and other delicate carbon-based materials . Laser-assisted metallization has demonstrated flexibility, effectiveness, and ability to produce sophisticated and complex structures with high reproducibility.…”

In this study, we explore the feasibility of a promising approach to fabricate conductive copper patterns with arbitrary topology on various dielectric substrates using direct laser metallization from deep eutectic solvents. We demonstrate the capability to print on industrially relevant dielectric materials, including polyimide, fiberglass plastic, and polytetrafluoroethylene (PTFE) substrates. We investigate the geometric and electrical characteristics of the resulting patterns and their composition. Our findings highlight the significant influence of the substrate material on both the formation rate of structures and their final properties. The characteristic resistance of the fabricated copper patterns is in the range from 0.23 to 1.64 Ω × mm2/m. The rate of pattern formation varied from 0.5 to 3.5 mm/s, depending on the substrate used.

“…Moreover, the DLW process has a great advantage in the tailoring and integration of functionally advanced nanodevices with a designed configuration. DLW has been demonstrated to be successful in fabricating various micro- and nanodevices for many applications [ 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Therefore, the introduction of DLW technology in the fabrication of QD–polymer nanocomposites is an effective choice to compensate for the existing deficiencies of conventional methods.…”

Promising direct laser writing (DLW) technology has been introduced to process functional quantum dot (QD)–polymer nanocomposites. The results reveal that after surface modification, the QDs are compatible with the SR399 monomer, and the homogeneous incorporation of QDs is accordingly obtained owing to the copolymerization and resultant cross-linking of QDs into SR399 resin under DLW processing with a laser wavelength (λ) of 532 nm. Moreover, compared with other scholars, we have proved that the surface modified QDs incorporated into the nanocomposites that can be successfully processed via DLW can reach a concentration of up to 150 mg/mL. Owing to the threshold behavior and nonlinear nature of the DLW process, it is feasible to modify the attendant exposure kinetics and design lines of any small size by selecting an appropriate laser power (P) and scan speed (v). The superfine feature size of 65 nm (λ/8) of the red QD–polymer suspended line can be tailored by applying the optimized P of 15 mW and v of 700 μm/s, and the finest green QD–polymer suspended line also reaches 65 nm (λ/8) with the optimized P of 14 mW and v of 250 μm/s used. Moreover, DLW processed QD–polymer structures present strong and homogeneous photoluminescence emission, which shows great potential for application in high-resolution displays, anti-counterfeit technology, and optical encryption. Additionally, the two types of long pass QD–polymer absorptive filters prepared by DLW exhibit superior optical performance with a considerably high transmittance of more than 90% for red QD–polymer block filter, and over 70% for green QD–polymer block filter in the transmittance region, which means that different filters with specific performance can be easily customized to meet the demand of various microdevices. Therefore, the DLW process can be applied to produce geometrically complex micro- and nanoscale functional structures, which will contribute to the development of advanced optoelectronic devices.

The direct laser writing (DLW) of photoluminescent metal clusters is inspiring intensive research in functional glasses. However, the impact of the host structure on cluster formation and visualization of DLW-induced clusters at the atomic scale remains challenging. In this work, we developed a highly photosensitive fluorophosphate glass matrix through fluorine incorporation. The addition of fluorine established a conducive environment for Ag+ ions before DLW and enhanced the availability of reducing agents and diffusion pathways during DLW. These advantages facilitate the formation of Ag quantum clusters (Ag QCs) dots under low-energy single-pulsed DLW. Increasing laser energy resulted in a combination of Ag QCs and glasses defect, forming a dot + ring photoluminescent pattern. To directly visualize the Ag QCs, we employed atom probe tomography (APT), a technique capable of mapping the spatial distribution and quantifying the number of Ag QCs. APT results demonstrated that DLW effectively halves the distance between adjacent Ag+ ions, leading to a significant increase in the abundance of Ag QCs with various aggregations, as well as a 31-fold increase in cluster density. The design concept and characterization enrich our understanding of Ag QCs behavior in glasses. This new knowledge opens up possibilities for the rational design of clusters confined in glasses and inspires their directed synthesis and various applications.
