Bi3+-containing semiconductors usually show rich optical and electronic properties due to the hybridization between 6s and 6p electronic components together with the lone pair in Bi3+ ions. In this work, an In3+-stabilized γ-Bi2O3 sillenite structure, Bi24InO37.5 (Bi12In0.5O18.75), was prepared...detailed
Sillenite bismuth ferrite (S-BFO) Bi25FeO40 was synthesized by a hydrothermal process and firstly adopted for the activation of peroxymonosulfate (PMS). Multiple characterization was conducted for the morphology and physicochemical features of S-BFO. Degradation of aquatic levofloxacin (LVF) was...detailed
Bismuth oxide based Bi12SiO20 dielectric ceramics were prepared via a solid state reaction process. The bismuth oxide of the ceramics was vaporized during the calcination and sintering process, and became non-stoichiometric Bi2O3 deficient sillenite compounds. Different amounts of Bi2O3 were add...detailed
Electronic, optical and energetic properties of antisite BiMO4 defect in the Bi12MO20 (M = Ti, Ge, Si) sillenite crystals have been investigated by means of the first-principles calculations on density functional theory level. The defect is studied in neutral, positive and negative charge state,...detailed
We report on the presence of photovoltaic effect in some Sillenite photorefractive crystals and compare their behavior with that of the well known photovoltaic LiNbO3:Fe crystal. Nonlinear photovoltaic behavior of these Sillenites are also reported here for the first time and explained by the pr...detailed
