“…[10,16] For example, silver nanoparticle (AgNP) inks have been commercialized [22] due to their printability and capacity to yield high-conductivity films which typically reach ≈3 × 10 7 S m −1 following high temperature (>200 °C) annealing. [23] Inks based on the in situ reduction of silver complexes can lower the processing temperature to ≈100 °C [24,25] however post-treatment is usually still needed to maximize the conductivity. [25,26] Similarly, particle-free reactive silver inks have shown high conductivity (>10 6 S m −1 ) when processed at room temperature, [27] however the solution-based nature of these inks may preclude them from use in porous heterostructures due to solute penetration into the lower layers.…”

Alternatively, networks of silver nanowires (AgNW) have been used in a range of device applications [28] and when printed, display conductivities up to 10 6 S m −1 [29,30] but plasma welding or sintering at over 200 °C [31] is typically required to maximize the network conductivity.…”

Although printed networks of semiconducting nanosheets have found success in a range of applications, conductive nanosheet networks are limited by low conductivities (<106 S m−1). Here, dispersions of silver nanosheets (AgNS) that can be printed into highly conductive networks are described. Using a commercial thermal inkjet printer, AgNS patterns with unannealed conductivities of up to (6.0 ± 1.1) × 106 S m−1 are printed. These networks can form electromagnetic interference shields with record shielding effectiveness of >60 dB in the microwave region at thicknesses <200 nm. High resolution patterns with line widths down to 10 µm are also printed using an aerosol‐jet printer which, when annealed at 200 °C, display conductivity >107 S m−1. Unlike conventional Ag‐nanoparticle inks, the 2D geometry of AgNS yields smooth, short‐free interfaces between electrode and active layer when used as the top electrode in vertical nanosheet heterostructures. This shows that all‐printed vertical heterostructures of AgNS/WS2/AgNS, where the top electrode is a mesh grid, function as photodetectors demonstrating that such structures can be used in optoelectronic applications that usually require transparent conductors.

“…where λ is the X-ray wavelength (Cu Kα, 0.154 nm) in nanometer (nm), β is the full width at half-maximum (FWHM) in radians, θ is the diffraction angle, and K is a constant related to crystallite shape, generally taken as 0.9. All samples exhibit the several diffraction peaks corresponded to (111), ( 200), ( 220), (311), and (222) planes of pure crystalline face-centered cubic (fcc) silver, respectively [54]. The peak of (111) plane was dominant, although Ag (111) and (220) peaks overlapped with XRD peaks associated with PET substrate.…”

Photo-Sintered Silver Thin Films by a High-Power UV-LED Module for Flexible Electronic Applications

In recent printed electronics technology, a photo-sintering technique using intense pulsed light (IPL) source has attracted attention, instead of conventional a thermal sintering process with long time and high temperature. The key principle of the photo-sintering process is the selective heating of a thin film with large light absorption coefficients, while a transparent substrate does not heat by the IPL source. Most research on photo-sintering has used a xenon flash lamp as a light source. However, the xenon flash lamp requires instantaneous high power and is unsuitable for large area applications. In this work, we developed a new photo-sintering system using a high-power ultraviolet light emitting diode (UV-LED) module. A LED light source has many merits such as low power consumption and potential large-scale application. The silver nanoparticles ink was inkjet-printed on a polyethylene terephthalate (PET) and photo-sintered by the UV-LED module with the wavelength of 365 and 385 nm. The electrical resistivity as low as 5.44 × 10−6 Ω·cm (just about three times compared to value of bulk silver) was achieved at optimized photo-sintering conditions (wavelength of 365 nm and light intensity of 300 mW/cm2).

“…In addition, previous studies show that at lower temperatures, the crystals are more likely to grow anisotropically. [33] As the temperature decreases, the anisotropic adsorption stability energy becomes more dominant in controlling the growth of Ag monomers on certain crystallographic planes, and the Ostwald ripening process is not significant in Ag nano-flowers due to slower surface diffusions.…”

Silver particles are key materials for the production of conductive inks, which are typically thermally sintered to obtain high conductivity. However, it remains a big challenge to achieve high conductivity at temperatures lower than 150 °C, for the protection of heat‐sensitive components in printed electronic devices. In this study, a novel frigid synthesis strategy at subzero temperature (Celsius) to produce Ag NPs with rich, rose‐like nanostructures (Ag nano‐flowers) is developed. The growth mechanism of Ag nano‐flowers under frigid conditions is analyzed and discussed. Due to the fine nanoscale structure of Ag nano‐flowers, they exhibit low sintering temperature below 120 °C. The electrical conductivity of printed Ag nano‐flower foil reaches 8.64 × 104 S cm−1 at 120 °C, and 1.20 × 105 S cm−1 at 150 °C. This study provides an attractive approach to the facile fabrication of Ag nano‐flowers with high electronic conductivity sintered at low temperatures and grants new insights into nanocrystallization under low‐temperature conditions.
