Pure ZnO:Eu 3+ nanoparticles (~50nm) were prepared by a solution combustion method. ZnO and Eu 2 O 3 were used as starting materials and dissolved in nitric acid. Citric acid was used as a fuel. The reaction mixture was heated at 350°C resulting into a rapid exothermic reaction yielding pure nanopowders. The atomic weight concentration of Eu 3+ doped in ZnO was 20%...
This paper embodies the result of the investigations carried out on the synthesis of zirconia‐ rare earth mixed oxide pigments: ZrCe1‐xYxO4‐δ and ZrCe1‐xPrxO4‐δ by the solution combustion method and their characterization by X‐ray powder diffraction, transmission electron microscopy, energy dispersive spectrometric analysis, thermal analysis, reflectance spectral data and surface area measurements...
