Electrical and chemical properties of vacancy-ordered lead free layered double perovskite nanoparticles.

In this work we synthesized vacancy-ordered lead-free layered double perovskite (LDP) nanoparticles. This structure consists of two layers of trivalent metal halide octahedra [B(III)X] separated by a layer of divalent metal [B(II)X] (B is a divalent or trivalent metal). The chemical formula of this structure is based on AB(II)B(III)X where A is Cs, B(III) is Bi, X is Cl and B(II) is a different ratio between Mn and Cd.
