This paper reports the luminescent response upconversion of zirconium oxide (ZrO2) nanoparticles doped with erbium (Er3+) and ytterbium (Yb3+) ions, synthesized by hydrothermal route. X ray diffraction (DRX) showed that the synthesized material presents the face centered cubic (FCC) structure. High resolution transmission electron microscopy (HRTEM) showed the presence of crystals size smaller than...
The aim of this work was to study the relationship between the crystalline structure, the mixed ionic–electronic conductivity and the calcium content in calcium-doped lanthanum manganites (CLM, La 1−x Ca x MnO 3 ) synthesized by reactive ball milling. Mechanosynthesis was employed to produce nanocrystalline CLM with varying calcium content (x=0–0.8 in increments of 0.1). Powders...
