## Description

- description: Layered perovskite-type compounds MCa2MnNb3TiO13 (M=K,Rb) were synthesized
    via a unique conventional solid-state reaction. The synthesis was conducted by
    thoroughly mixing a layered perovskite precursor, MCa2Nb3O10, with MnTiO3 in a
    stoichiometric molar ratio, followed by high-temperature calcination at 1473 K.
    Compositional and structural characterizations involving elemental analysis and
    Rietveld refinement confirmed that the perovskite slabs in the host layers are
    four [Nb,Ti]O6 octahedra thick, with Ca2+ and Mn2+ ions occupying the A-sites.
    Subsequent exfoliation by shaking in an aqueous TBOH solution yielded a light
    brown suspension. AFM revealed the presence of numerous micrometer-sized 2D nanosheets
    with a uniform thickness of approximately 2.0 nm, indicating complete exfoliation
    into single perovskite layers. Further in-depth analysis via in-plane and out-of-plane
    XRD, as well as XPS, confirmed that the obtained 2D materials correspond to individual
    perovskite layers derived from the Mn-substituted parent phase.
