Influence of Microwave Heating on the Growth of Gadolinium-Doped Cerium Oxide Nanorods
TL;DR: In this paper, the authors demonstrate that the use of microwave heating during hydrothermal treatment drastically decreases the treatment time required to obtain gadolinium-doped ceria nanorods and that the oriented attachment is the dominant mechanism responsible for anisotropic growth.

Rietveld refinement, cluster modelling, growth mechanism and photoluminescence properties of CaWO4: Eu3+ microcrystals
R. F. Gonçalves,L. S. Cavalcante,I. C. Nogueira,Elson Longo,M. J. Godinho,M. J. Godinho,Júlio C. Sczancoski,Valmor Roberto Mastelaro,Ivo M. Pinatti,Ieda Lúcia Viana Rosa,Ana Paula Marques +10 more
TL;DR: In this article, the photoluminescence properties of the Eu3+ ions in CaWO4 were studied as well as the chromaticity coordinates and lifetimes of these compounds.

Ionic conductivity of Bi4Ti0.2V1.8O10.7 polycrystalline ceramics obtained by the polymeric precursor route
TL;DR: In this article, an analysis of X-ray diffraction patterns revealed that the Bi 4 Ti 0.2 V 1.8 O 10.7 phase was formed by heat-treating the composition at 650 °C for 3 h, and the resulting powder presented a surface area of about 5.1 m 2 g −1.

Crystal growth and photoluminescence of europium-doped strontium titanate prepared by a microwave hydrothermal method
R. F. Gonçalves,Ana Paula de Moura,M. J. Godinho,Elson Longo,M.A.C. Machado,D.A. de Castro,M. Siu Li,Ana Paula Marques +7 more
TL;DR: In this paper, europium-doped strontium titanate (SrTiO 3 :Eu 3+ ) was successfully synthesized using a co-precipitation method at room temperature with processing in a microwave-hydrothermal system at 140°C for 30 min.
