However, the high efficiencies of 0D In-based OIMHs are all dependent on Sb doping in the existing literature. Here, we report a novel 0D In-based OIMH (C<sub>10<\/sub>H<sub>22<\/sub>N<sub>2<\/sub>)<sub>2<\/sub>In<sub>2<\/sub>Br<sub>10<\/sub>, which exhibits intrinsic broadband emission (610 nm), and the photoluminescence quantum yield (PLQY) can reach 70% without Sb doping. (C<sub>10<\/sub>H<sub>22<\/sub>N<sub>2<\/sub>)<sub>2<\/sub>In<sub>2<\/sub>Br<sub>10<\/sub>&nbsp;shows a typical 0D structure with three different In\u2013Br polyhedra (two octahedra and one tetrahedron) separated by large organic cations. Based on the optical property measurements and theoretical calculations, we demonstrate that (C<sub>10<\/sub>H<sub>22<\/sub>N<sub>2<\/sub>)<sub>2<\/sub>In<sub>2<\/sub>Br<sub>10<\/sub>&nbsp;is an indirect semiconductor with a band gap of 3.74 eV, and the In\u2013Br inorganic moiety is primarily responsible for the intense emission of (C<sub>10<\/sub>H<sub>22<\/sub>N<sub>2<\/sub>)<sub>2<\/sub>In<sub>2<\/sub>Br<sub>10<\/sub>. Interestingly, the unique double octahedral configuration in (C<sub>10<\/sub>H<sub>22<\/sub>N<sub>2<\/sub>)<sub>2<\/sub>In<sub>2<\/sub>Br<sub>10<\/sub>&nbsp;may enhance the structural distortion and stimulate the self-trapped excitons (STEs), leading to the related high PLQY. Our work provides a novel 0D In-based OIMH with high-efficiency intrinsic emission, which is helpful for understanding the structure\u2013PL relationships of hybrid halides.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Inorg.
