“…Pasquarelli et al have demonstrated amorphous/nanocrystalline IZO films prepared by ultrasonic spray deposition from formate precursors with annealing at 300-400 1C. 106,264 Solutions consisted of In(HCOO) 2 (OH) and Zn(HCOO) 2 Á2H 2 O in a methanol-water-acid (6 : 1 : 0.2 vol) mixture. Films were amorphous at indium contents as low as 40 at% but with low conductivities of o50 S cm À1 .…”

This critical review focuses on the solution deposition of transparent conductors with a particular focus on transparent conducting oxide (TCO) thin-films. TCOs play a critical role in many current and emerging opto-electronic devices due to their unique combination of electronic conductivity and transparency in the visible region of the spectrum. Atmospheric-pressure solution processing is an attractive alternative to conventional vacuum-based deposition methods due to its ease of fabrication, scalability, and potential to lower device manufacturing costs. An introduction into the applications of and material criteria for TCOs will be presented first, followed by a discussion of solution routes to these systems. Recent studies in the field will be reviewed according to their materials system. Finally, the challenges and opportunities for further enabling research will be discussed in terms of emerging oxide systems and non-oxide based transparent conductors (341 references).

“…Black powders have been observed during the decomposition of indium formate precursors and was attributed to the presence of metallic indium using XRD. 22 However, no metallic indium was detected by XRD in the black material from In 5 O(OPr i ) 13 . This would suggest that the black-to-yellow color transition is instead the result of a conversion from a substoichiometric oxide to a more stoichiometric oxide with temperature.…”

“…The sintered nickel nanoparticle inks can obtain an electrical resistivity ranging from 20 to 50 µΩ cm, which are applicable for fabricating conductive tracks and patterns. Pasquarelli et al also reported depositing nickel nanoparticle inks onto glass and zinc oxide with an inkjet printer to fabricate electrode contacts for solar cell applications. Possible applications with nickel nanoparticle inks may include temperature sensors, inductors and microheaters.…”

Metallic nanoparticle inks are readily obtainable from the commercial market and are commonly used for fabricating conductive tracks and patterns due to their relatively higher electrical conductivity as compared to other types of inks. These metallic nanoparticle inks are made up of electrically conductive metallic nanoparticles suspended in liquid mediums, with particle size ranging from 1 to 100 nm. However, there are also diverse types of metallic nanoparticle inks in the market (for instance, silver nanoparticle inks, gold nanoparticle inks, and copper nanoparticle inks). Metallic nanoparticle inks of different material compositions can directly influence the final electrical, material, and mechanical properties of the printed patterns. This paper presents an overview of the different types of metallic nanoparticle inks used for the 3D printing of electronics. The strengths and weaknesses of each type of ink are critically reviewed. The challenges and potentials of metallic nanoparticle inks in 3D printed electronics are also discussed. Metallic Nanoparticle InksMetallic nanoparticle inks are suspensions of metallic nanoparticles in liquid mediums (see Figure 2a), in which individual metallic nanoparticle is encapsulated in a layer of insulating organic additives and stabilizing agents (see Figure 2b). The encapsulating organic additives and stabilizing agents help prevent the metallic nanoparticles from agglomeration, but at the same time, also impede the flow of electrons from particles to particles. Therefore, sintering processes are required to remove The three-dimensional (3D) printed electronics additive manufacturing industry sector has grown substantially in the past few years, and there is increasing demand for different types of metallic nanoparticle inks in electronics printing for various applications. Metallic nanoparticle inks are commonly used for fabricating conductive tracks and patterns due to their relatively high electrical conductivity as compared to other types of inks, and they can be further categorized into single-element metallic nanoparticle inks, alloy metallic nanoparticle inks, metallic oxide nanoparticle inks, and core-shell bimetallic nanoparticle (BNP) inks. It is critical to gain a deep understanding of the metallic nanoparticle inks used in 3D printed electronics as the material properties of these inks can directly affect the final electrical and mechanical properties of the printed patterns. This review presents an overview of the available metallic nanoparticle inks used for 3D printing of electronics, and critically reviews the strengths and weaknesses of each type of ink. Finally, the challenges of metallic nanoparticle inks in 3D printed electronics are also discussed along with the future outlook for 3D printed electronics.
