In this work, a series of compounds (TMEDA)<small><sub>3<\/sub><\/small>(Sb<small><sub><em>x<\/em><\/sub><\/small>Bi<small><sub>1\u2212<em>x<\/em><\/sub><\/small>)<small><sub>2<\/sub><\/small>Cl<small><sub>12<\/sub><\/small>\u00b7H<small><sub>2<\/sub><\/small>O (0.1 \u2264&nbsp;<em>x<\/em>&nbsp;\u2264 0.6) (TMEDA =&nbsp;<em>N<\/em>,<em>N<\/em>,<em>N<\/em>\u2032-trimethylethylenediamine) were synthesized. The incorporation of Sb<small><sup>3+<\/sup><\/small>&nbsp;greatly enhanced the photoluminescence quantum yield of (TMEDA)<small><sub>3<\/sub><\/small>Bi<small><sub>2<\/sub><\/small>Cl<small><sub>12<\/sub><\/small>\u00b7H<small><sub>2<\/sub><\/small>O from 1% to 38%. The variation in the degree of distortion of the inorganic octahedra and the relatively suitable distances between metal ions are considered to be the reasons for the intense emission. (TMEDA)<small><sub>3<\/sub><\/small>(Sb<small><sub><em>x<\/em><\/sub><\/small>Bi<small><sub>1\u2212<em>x<\/em><\/sub><\/small>)<small><sub>2<\/sub><\/small>Cl<small><sub>12<\/sub><\/small>\u00b7H<small><sub>2<\/sub><\/small>O (0.1 \u2264&nbsp;<em>x<\/em>&nbsp;\u2264 0.6) exhibited a yellow phosphorescence emission at 605 nm and 595 nm under excitation at 305 nm and 375 nm, respectively. With the incorporation of Sb<small><sup>3+<\/sup><\/small>, changes in the emission intensity under different excitation wavelengths showed different trends. Thus, we attribute the yellow broadband emissions to the triplet emission of Bi<small><sup>3+<\/sup><\/small>&nbsp;and Sb<small><sup>3+<\/sup><\/small>. Finally, we combined (TMEDA)<small><sub>3<\/sub><\/small>(Sb<small><sub>0.5<\/sub><\/small>Bi<small><sub>0.5<\/sub><\/small>)<small><sub>2<\/sub><\/small>Cl<small><sub>12<\/sub><\/small>\u00b7H<small><sub>2<\/sub><\/small>O with commercial phosphors and a near-ultraviolet light-emitting diode chip to prepare a white-light-emitting diode device, which exhibited a high color-rendering index of 94.4. The aim of our work was to investigate the structural effects of the photoluminescence of Sb<small><sup>3+<\/sup><\/small>-doped OIMHs and to further explore ways to improve the Sb<small><sup>3+<\/sup><\/small>&nbsp;emission efficiency in the field of photoluminescence of OIMHs.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>J.
