(PPA)<sub>6<\/sub>InBr<sub>9<\/sub>, (PBA)<sub>2<\/sub>SbBr<sub>5<\/sub>, and (PBA)<sub>2<\/sub>SbI<sub>6<\/sub>&nbsp;have experimental optical band gaps of \u223c3.16, \u223c2.24, and 1.48 eV, respectively. (PPA)<sub>6<\/sub>InBr<sub>9<\/sub>&nbsp;exhibits bright-orange light emission centered at 642 nm with a full-width at half-maximum of 179 nm (0.51 eV) and a Stokes shift of 277 nm (1.46 eV). After Sb<sup>3+<\/sup>&nbsp;doping, the peak position did not change, and the photoluminescence quantum yield increased significantly from 9.2 to 53.0%. The efficient emission of Sb:(PPA)<sub>6<\/sub>InBr<sub>9<\/sub>&nbsp;stems from the isolated ns<sup>2<\/sup>&nbsp;luminescent center and strong electron\u2013phonon coupling, making the spin-forbidden&nbsp;<sup>3<\/sup>P<sub>1<\/sub>\u2013<sup>1<\/sup>S<sub>0<\/sub>&nbsp;observable. By combining commercial blue and green phosphors with orange-red-light-emitting (PPA)<sub>6<\/sub>In<sub>0.99<\/sub>Sb<sub>0.01<\/sub>Br<sub>9<\/sub>, a white-light-emitting diode was constructed, with the color-rendering index reaching up to 92.3. Our work highlights three novel 0D OIMHs, with chemical doping of Sb<sup>3+<\/sup>&nbsp;shown to significantly enhance the luminescence properties, demonstrating their potential applications in solid-state lighting.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Inorg.
