“…Our x-ray result for Bi 25 FeO 39 (10.184(2)Å) agrees with Radaev et al 50 and yields a larger unit cell volume for this compound than the Ti 4+ and Ga 3+ sillenite. Therefore, our x-ray results, on samples synthesized with the same methods, show that the unit cell volume increases with larger M cation and the Raman spectra (Fig.…”

Here, we report the structure evolution, magnetic and ferroelectric properties in Co-doped 4- and 3-layered intergrowth Aurivillius compounds Bi4NdTi3Fe1-xCoxO15-Bi3NdTi2Fe1-xCoxO12-δ. The compounds suffer a structure evolution from the parent 4-layered phase (Bi4NdTi3FeO15) to 3-layered phase (Bi3NdTi2CoO12-δ) with increasing cobalt doping level from 0 to 1. Meanwhile the remanent magnetization and polarization show opposite variation tendencies against the doping level, and the sample with x = 0.3 has the largest remanent magnetization and the smallest polarization. It is believed that the Co concentration dependent magnetic properties are related to the population of the Fe3+ -O-Co3+ bonds, while the suppressed ferroelectric polarization is due to the enhanced leakage current caused by the increasing Co concentration. Furthermore, the samples (x = 0.1–0.7) with ferromagnetism show magnetoelectric coupling effects at room temperature. The results indicate that it is an effective method to create new multiferroic materials through modifying natural superlattices.

“…It is reported [7] that Bi 25 FeO 40 also has the structure of sillentite with M=Bi 0.5 Fe 0.5 . The umbrella-like Bi 3+ O 3 groups [8] in Bi 25 FeO 40 crystal is also considered to eliminate the recombination of electron-hole pairs and its photocatalyst behavior is worth looking forward to.…”

Sillenite Bi 25 FeO 40 crystallites have been fabricated via a sol-gel approach. X-ray diffraction results show that single-phase Bi 25 FeO 40 can be synthesized at the annealing temperature of 600 o C with the help of PEG additive. The amount of additives and the annealing temperature has great effects on the formation of phase pure Bi 25 FeO 40 crystallites. The morphologies of Bi 25 FeO 40 crystallites were observed by SEM techniques. UV-vis diffuse reflectance spectroscopy indicated the good visible light absorption of Bi 25 FeO 40 crystallites. The photo-catalytic activity of Bi 25 FeO 40 powders was evaluated by the degradation of methyl orange solution assisted by H 2 O 2 under UV-Vis light and Vis-only light irradiation, which suggested that Bi 25 FeO 40 crystallites are potential photocatalytic materials.
