Abstract
Our research group has developed a novel process for synthesizing calcium stannate in a CO–CO2 atmosphere at lower temperature (<1000 °C). The formation behavior of calcium stannate was clarified in previous publications. In this study, the properties of CaSnO3, Ca2SnO4 and Eu-doped Ca2SnO4 synthesized under different atmospheres were further characterized. The results indicated CaSnO3 exhibited good photocatalytic performance in the degradation of Rhodamine B. As a dielectric material, Ca2SnO4 synthesized under CO–CO2 atmosphere had higher dielectric constant and lower dielectric tangent loss compared with that synthesized under air. In addition, the photoluminescence properties of Eu-doped Ca2SnO4 were close to that synthesized under air.
