3D‐Architected Alkaline‐Earth Perovskites

Jędrzej P. Winczewski,

et al.

Abstract: Three‐dimensional (3D) ceramic architectures are captivating geometrical features with an immense demand in photonics. Here, we develop an additive manufacturing (AM) approach for printing alkaline‐earth perovskite 3D microarchitectures. The newly developed approach enables custom‐made photoresists suited for two‐photon lithography, permitting the production of alkaline‐earth perovskite (BaZrO3, CaZrO3, and SrZrO3) 3D structures shaped in the form of octet‐truss lattices, gyroids or inspired architectures like… Show more

“…However, though current methods such as photochemical bonding of colloidal inorganic nanocrystals significantly expanding the materials range for femtosecond laser-based 3D printing, the intrinsic size limit of nanocrystals imposes constraints on surface roughness, limiting their suitability for super-fine optical elements at present. Additionally, the utilization of 2D materials [130], perovskite materials [225], upconversion materials, or molecular crystals can enable nonlinear optical conversion, allowing the capture of x-ray, UV, and infrared information in 3D-printed imaging systems [231]. Specific inks designed for colorful imaging and light-blocking, as well as semiconductors for optoelectronic imaging devices, represent other avenues of exploration.…”

“…[1] The recent development of photoresins tailor-made to print metal-organic microstructures opened an avenue for the AM of ceramic microarchitectures. [2] The ceramic architectures are obtained upon annealing the printed preceramic architecture of arbitrary design in the air, retaining the spatial architecture features in the yielded replica. Some recent literature examples include TiO 2, [3] ZnO, [4] and ZrO 2 .…”

“…[5,6] With the advancements in a new field, 3D ceramic for microoptics, chemists, and materials scientists can contribute to understanding phase transition effects due to dopants and generate insights in defect chemistry optically, which has not been sufficiently addressed in detail for AM ceramic architectures. [2] Introducing substitutional impurities in the ZrO 2 crystal lattice is a promising route from a defect chemistry perspective. [6,[21][22][23][24] DOI: 10.1002/adem.202400187…”
