description | Organic–inorganic hybrid halides and their analogs that exhibit efficient broadband emission from self-trapped excitons (STEs) offers an unique pathway towards realization of highly efficient white light sources for lighting applications. An appropriate dilution of ns<sup>2</sup> ions into a halide host is essential to produce auxiliary emissions. However, the realization of ns<sup>2</sup> cation-based halides phosphor that can be excited by blue light-emitting diode (LED) is still rarely reported. In this study, a zero-dimensional Te-based single crystal (C<sub>8</sub>H<sub>20</sub>N)<sub>2</sub>TeCl<sub>6</sub> was synthesized, which exhibits a yellow-orange emission centered at 600 nm with a full width at half maximum of 130 nm upon excitation under 437 nm. Intense electron–phonon coupling was confirmed in the (C<sub>8</sub>H<sub>20</sub>N)<sub>2</sub>TeCl<sub>6</sub> single crystal and the light emitting mechanism is comprehensively discussed. The results of this study are pertinent to the emissive mechanism of Te-based hybrid halides and can facilitate discovery of unidentified metal halides with broadband excitation features. |
