In the survey of photoluminescence properties of rare-earth doped alkaline-earth stannates, CaSnO3 was found to show intense white luminescence by Pr doping and green luminescence by Tb-Mg codoping. Pr-doped CaSnO3 showed not only a red emission line originating from the f-f transition from D2 to H4 state, which is observed in Pr doped CaTiO3 or SrTiO3, but also an intense blue-green line assig...

We report density functional studies of electron rich interfaces between KTaO3 or KNbO3 and CaSnO3 or ZnSnO3 and in particular the nature of the interfacial electron gasses that can be formed. We find that depending on the details these may occur on either the transition metal or stannate sides of the interface and in the later case can be shifted away from the interface by ferroelectricity. We...

In this communication, preliminary structural and detailed electrical characteristics of the CaSnO3/CaSeO3-modified Bi0.5Na0.5TiO3 ceramics a general chemical composition (1–2x) [Bi0.5Na0.5TiO3] + x (CaSnO3) (CaSeO3) with = 0, 0.05, 0.10, 0.15, has been prepared by high-temperature solid-state reaction method calcination sintering temperature 925 °C 950 °C, respectively, for 5 h. Structural par...

in this paper, calcium stannate nanoparticles were synthesized by a fast and simple co-precipitation procedure. for casno3 preparation ammonia was used as precipitation agent. the effect of various surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. by changing in ca(sal)2 as a new precursor different morphologies were obtained. ligand as a capp...

BaTiO3-based piezoelectric ceramics have attracted considerable attention in recent years due to their tunable phase structures and good properties. In this work, the (1 ? x)BaTiO3?xCaSnO3 (0.00 ? x 0.16, abbreviated as BT?xCS) solid solutions, were prepared by traditional solid-state reaction methods. The transitions, microstructure, dielectric, piezoelectric, ferroelectric properties of BT-xC...
