Nanoparticles of erbium-doped yttria (Er:Y2O3) are important precursors to transparent ceramics for high-power solid-state lasers systems. As structure influences properties and, subsequently, performance the purpose of this work is to compare the mo

LaF3 nanoparticles were grown in aqueous solutions containing different surfactants to realize stronger absorption cross-sections and energy transfer to the optical center. Benzoic acid and phthalic acid were selected as the surfactants attached to t

The adhesive joint between silica nanoparticles and ultrathin poly(vinylpyridine) (PVP) layers (thickness between 3 and 100 nm) was tested using the cantilever of an atomic force microscope. Specifically, the strength of the adhesive bond (or practic

Complex core-shell architectures are implemented within LaF 3 nanoparticles to allow for a tailored degree of energy transfer (ET) between different rare earth dopants. By constraining specific dopants to individual shells, their relative distance to

In this article, we report on the fabrication of 0.3-μm average grain-sized transparent yttria ceramics using a modified two-step sintering approach. This process yielded full densification of the yttria ceramics with a drastically reduced grain gro
