Access to metastable complex ion conductors via mechanosynthesis: Preparation, microstructure and conductivity of (Ba,Sr)LiF3 with inverse perovskite structure

Düvel, A.; Wegner, S.; Efimov, K.; Feldhoff, A.; Heitjans, Paul; Wilkening, Martin (Cambridge : Royal Society of Chemistry, 2011)

Highly metastable Ba1−xSrxLiF3 (0 < x ≤ xmax ≈ 0.4) with an inverse perovskite structure analogous to that of BaLiF3 was synthesized by soft mechanical treatment of BaF2 and LiF together with SrF2 at ambient temperature. ...
Improved charge carrier separation in barium tantalate composites investigated by laser flash photolysis

Schneider, Jenny; Nikitin, Konstantin; Wark, Michael; Bahnemann, Detlef W.; Marschall, Roland (Cambridge : Royal Society of Chemistry, 2015-12-15)

Charge carrier dynamics in phase pure Ba5Ta4O15 and in a Ba5Ta4O15–Ba3Ta5O15 composite have been studied by means of diffuse reflectance laser flash photolysis spectroscopy in the presence and absence of an electron donor, ...
Sol–gel synthesis and structural characterization of band gap engineered ferroelectric perovskite oxide potassium sodium barium nickel niobate

Balanov, Vasilii A.; Zhao, Zhijun; Pan, Mingjing; Feldhoff, Armin; Bai, Yang (Dordrecht [u.a.] : Springer Science, 2020)

Ferroelectric materials with engineered thus visible-range optical band gaps are increasingly researched in recent years, triggering potentially new applications in solar cells, opto-ferroelectric devices, multifunctional ...
