Dion–Jacobson A′MⁱⁱⁱNaNb₃O₁₀ (A′ = Rb, Cs; M(iii) = Sm, Bi) and RbSmNa₂Nb₄O₁₃ layered perovskites and their luminescent function

Abstract

Layered perovskites offer an ideal playground for researchers to tailor their multiple functions through cation and anion modifications; hence, research on them is vigorously pursued. The present study explored multivalent...

Intrinsic stability of perovskite materials and their operational stability in light-emitting diodes

“…MHPs are semiconductor materials with the general structural formula ABX 3 , where A represents an organic/inorganic cation such as methyl ammonium (CH 3 NH 3 + ), formamidinium (CH 3 C(NH)NH 3 + ), phenylethyl ammonium (C 6 H 5 CH 2 CH 2 NH 3 + ) or inorganic alkali cations like Cs + , Rb + , and their cocktail compositions. 9–12 B is the central metal atom in the MHP crystal structure and is commonly Pb 2+ , Sn 2+ , Zn 2+ , or Cu 2+ . The third X is the halide ion (Cl − , Br − , I − ).…”
