Abstract

This research project will focus on the study and development of ceramic materials of CuWO4 and Fe2TiO5 compositions for shaping discs with 2 inches in diameter and 3 mm thick as target for deposition of nanoparticles by magnetron sputtering method. CuWO4 and Fe2TiO5 compositions will be synthesized via solid-state reaction. The choice for solid-state reaction is due to the method being well known for the preparation of "large scale" ceramic materials and being considered simple, low cost and good reproducibility of the synthesis. The discs will be used as targets to deposit very small nanoparticles by magnetron sputtering technique, to produce Tandem junction with SrTiO3 and NaTaO3 supports for the artificial photosynthesis reaction.
