Transition from Dion-Jacobson hybrid layered double perovskites to 1D perovskites for ultraviolet to visible photodetection.

ABSTRACT: New perovskite phases having diverse optoelectronic properties are the need of the hour. We present five variations of R₂AgM(iii)X₈, where R = NH₃C₄H₈NH₃ (4N4) or NH₃C₆H₁₂NH₃ (6N6); M(iii) = Bi³⁺ or Sb³⁺; and X = Br^- or I^-, by tuning the composition of (4N4)₂AgBiBr₈, a structurally rich hybrid layered double perovskite (HLDP). (4N4)₂AgBiBr₈, (4N4)₂AgSbBr₈, and (6N6)₂AgBiBr₈ crystallize as Dion-Jacobson (DJ) HLDPs, whereas 1D (6N6)SbBr₅, (4N4)-BiI and (4N4)-SbI have trans-connected chains by corner-shared octahedra.
