Sb<sup>3+</sup> dopant triggered highly efficient emission in zero-dimensional organic–inorganic hybrid metal halides
Hybrid luminescent metal halides have attracted considerable attention for their structural diversity and versatility in photonic applications. Herein, we fabricate Sb<sup>3+</sup> doped organic-inorganic hybrid metal halides (DMA)<sub>2</sub>CsInCl<sub>6</sub> (DMA = [CH<sub>3</sub>NH<sub>2</sub>CH<sub>3</sub>]<sup>+</sup>) single crystal. Under ultraviolet light excitation, the crystals yield bright green emission at 550 nm with near-unity photoluminescence quantum efficiency (PLQY), which is attributed to the strong electronegativity and ns<sup>2</sup> lone pairs of Sb<sup>3+</sup> dopants. Given the slender rod-shaped semblance, bright green emission, near-unity PLQY, and large Stokes shift, Sb<sup>3+</sup>-doped (DMA)<sub>2</sub>CsInCl<sub>6</sub> allows the potential optical waveguide applications.
