Electrical and microstructural properties of CaTiO3-doped K1/2Na1/2NbO3-lead free ceramics
(Indian Acad Sciences, 2011-10-01)
Microstructure, electrical properties and dielectric behaviour of K1/2Na1/2NbO3 (KNN) and CaTiO3-modified K1/2Na1/2NbO3 (CTO-KNN) systems, were investigated. Discs doped with 0 to 0-55% mol of CaTiO3 (CTO) were sintered ...

New materials based on modified synthetic Nb2O5 as photocatalyst for oxidation of organic contaminants
(Elsevier B.V., 2008-12-15)
Novel materials based on niobia (Nb2O5) destined to oxidize an organic compound in aqueous medium via heterogeneous photocatalysis after chemical modification were synthesized. Niobia was modified by the doping with ...

Enhanced visible light photocatalytic performance of SnO2 nanoparticle co-doped with (Co, Nb) for organic dye degradation
(2020-07-01)
Fast electron–hole recombination rate, lower free radical generation, unsuitable valence band maximum (VBM) and conduction band minimum (CBM) position of SnO2 nanoparticle are the shortfalls in achieving a superior ...
Secondary phases in Nb-doped BaTiO3 ceramics
(Elsevier B.V., 2002-01-01)
In this work, the effect of Nb2O5 addition on the microstructure of BaTiO3 was studied. From XRD diagrams, a diminution in tetragonality parameters with an increase in dopant concentration was observed. In order to determine ...
Near infrared emission at 1000 nm from nanostructured Pr3+/Yb3+ Co-doped SiO2-Nb2O5 for solar cell application
(2015-12-01)
Energy conversion, involving UV and Vis absorption to generate near infrared (NIR) emission at 1000 nm from nanostructured Pr3+/Yb3+ co-doped SiO2-Nb2O5 for solar cell application was the main focus of this work. The ...
