Oxygen isotope effect in the Ruddlesden-Popper phases
Bulletin of the Russian Academy of Sciences: Physics, 2009The oxygen isotope effect in ceramic samples of bilayer manganites (La1−zPrz)1.2Sr1.8Mn216–18O7(z = 0, 0.3) has been investigated. The real and imaginary parts of the magnetic susceptibility have been measured and a significant (more than 20 K) decrease in the ferromagnetic transition temperature upon oxygen isotope substitution 16O—18O is found.

Evaluation of the band-gap of Ruddlesden–Popper tantalates
Computational Materials Science, 2014Abstract Tantalum–oxide based compounds of the K 2 [Ln n − 1 Ta n O 3 n +1 ] cation-deficient Ruddlesden–Popper series are promising compounds as water splitting photocatalysts for hydrogen production. In this work the role of the lanthanide (Ln = La, Pr and Nd) in the K 2 LnTa 3 O 10 tantalate for the photocatalytic mechanism is studied ...

Halide Segregation in Ruddlesden-Popper Perovskites
2022Ruddlesden-Popper perovskites (RPPs) have shown promise as stable alternative to conventional 3D perovskites (PVKs), which are well-known to suffer from instability introduced, among others, by light exposure. Mixed-halide PVKs, in fact, display a phenomenon known as halide segregation, where illumination is followed by ion migration and formation of ...

Synthesis and characterization of a Ruddlesden–Popper compound: Sr3FeMoO7
Journal of Solid State Chemistry, 2005A powder sample of Sr{sub 3}FeMoO{sub 7} was synthesized by solid-state reaction in reduced atmosphere (5% H{sub 2}/Ar). At room temperature, Sr{sub 3}FeMoO{sub 7} crystallizes in a typical Ruddlesden-Popper (n=2) structure in the space group I4/mmm, a=3.9309(2)A and c=20.435(2)A.

White-light emitting Ruddlesden-Popper perovskites
2021Recently, owing to their excellent optoelectronic properties combined with an enhancedmaterial stability, two-dimensional (2D) organic halide perovskites have emerged as an attractive alternative to 3D perovskites for photovoltaics . More, their ability to emit white-light at room temperature with a good color rendering projected this family of ...

Enhanced magnetoresistance in the Ruddlesden?Popper compound Sr3Fe1.5Co0.5O6.67
Journal of Magnetism and Magnetic Materials, 2003Abstract We report the synthesis of the Ruddlesden–Popper material Sr 3 Fe 1.5 Co 0.5 O 6.67 (a compound usually obtained under high-pressure conditions) by a simpler normal pressure liquid-mix method and its structural characterization by means of X-ray powder diffraction.
