Abstract Zirconium-based compounds have considerable physical and chemistry stability which provides a large amount of scientific and technological applications. These compounds have been shown effective to convert ionizing radiation in electromagnetic emissions in the visible region. Due to this property the Barium Zirconate (BaZrO3, abbreviated as BZO) is a promising compound to obtain new materials. For this, the use of the interface of the particles with other materials can be a good option for the increase of the material properties. Among the compounds , the Zinc Sulfide (ZnS) is interesting alternative for the surface modification of the material to be very versatile and have a high luminescence intensity (including radioluminescence). Therefore, this project aims to study and analyze the synthesis of BZO and BZO with ZnS clusters in the surface via microwave-assisted hydrothermal and solvothermal process. The characterizations of the samples will be made by X-ray diffraction, Ultraviolet-visible spectroscopy, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, photoluminescence spectroscopy and radioluminescence spectroscopy. The core-shell system will be modeled using ab initio periodic quantum-mechanical techniques in order to provide information about the structural and electronic arrangement of the system confirming the experimental data. | |
