Abstract
Inkjet printing of metal nitrate precursors and subsequent annealing offers a facile and scalable route toward tailoring metal oxides in well-defined patterns. In the following work, an ink formulation comprised of yttrium nitrate hexahydrate, europium nitrate hexahydrate, and urea was printed onto borosilicate glass and stainless steel 304 substrates to study the surface reaction and interface evolution after annealing in an air or N2 environment. A QR code was fabricated with luminescent europium-doped yttrium oxide droplets to demonstrate the user-defined patterning capability of the inkjet printing technique, in which an invisible pattern to the naked eye was achieved for the oxide deposited on stainless steel. X-ray photoelectron spectroscopy reveals the reaction evolution from the yttrium nitrate precursor to yttrium oxide and yields insight into the potential role of cation diffusion and thermal expansion mismatch in governing the adhesion properties of the oxide layer.
期刊介绍:
Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry.
The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
