Abstract
We have studied the effect of small Cr2O3 and Cr3+ additions on the optical properties of high-purity alumina-based powders and photocurable slurries for 3D printing. The polymerization depth of the slurries has been shown to strongly depend on the amount of the coloring additive in the Al2O3 powders. Using digital light processing (DLP) 3D printing followed by high-temperature sintering, we have obtained thin-walled planar samples of high-density periodic-structure ceramics and studied their microstructure and luminescence properties. Their photoluminescence spectrum contains a sharp strong line in the red spectral region, at 694 nm (characteristic line of ruby). The luminescence decay curves showed single-exponential behavior with a decay time of ~3.7 ms.
期刊介绍:
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
