Аннотация: <jats:title>Abstract</jats:title><jats:p>Hybrid metal halides (HMHs) have emerged as a promising platform for optically functional crystalline materials, but it is extremely challenging to thoroughly elucidate the electron transition coupled to additional ligand emission. Herein, to discover sequences of lead-free HMHs with distincПоказать полностьюt optically active metal cations are aimed, that is, Sb<jats:sup>3+</jats:sup> (5s<jats:sup>2</jats:sup>) with the lone-pair electron configuration and In<jats:sup>3+</jats:sup> (4d<jats:sup>10</jats:sup>) with the fully-filled electron configuration. (Me<jats:sub>2</jats:sub>NH<jats:sub>2</jats:sub>)<jats:sub>4</jats:sub><jats:italic>M</jats:italic>Cl<jats:sub>6</jats:sub>·Cl (Me = −CH<jats:sub>3</jats:sub>, <jats:italic>M</jats:italic> = Sb, In) exhibits the superior temperature/component-dependent luminescence behaviors resulting from the competition transition between triplet-states (T<jats:sub>n</jats:sub>-S<jats:sub>0</jats:sub>) self-trapped excitons (STEs) of inorganic units and singlet-state (S<jats:sub>1</jats:sub>-S<jats:sub>0</jats:sub>) of organic cations, which is manipulated by the optical activity levels of [SbCl<jats:sub>6</jats:sub>]<jats:sup>3−</jats:sup> and [InCl<jats:sub>6</jats:sub>]<jats:sup>3−</jats:sup>. The bonding differences between Sb<jats:sup>3+</jats:sup>/In<jats:sup>3+</jats:sup> and Cl<jats:sup>−</jats:sup> in terms of electronic excitation and hybridization are emphasized, and the different electron-transition mechanisms are established according to the PL spectra at the extreme temperature of 5 to 305 K and theoretical calculations. By fine-tuning the B-site Sb<jats:sup>3+</jats:sup>/In<jats:sup>3+</jats:sup> alloying, the photoluminescence quantum yield (PLQY = 81.5%) and stability are optimized at 20% alloying of Sb<jats:sup>3+</jats:sup>. This research sheds light on the rules governing PL behaviors of HMHs, as well as exploring the optical-functional application of aviation temperature sensors and access-control systems.</jats:p>
