“…The absorption bands at 260 nm (C band) are derived from the 1 S 0 ( 1 A 1g ) → 1 P 1 ( 1 T 1u ) allowed transition. The above bands are consistent with the ns 2 electron transition pattern in Sb 3+ -doped OIMHs. ,− The PLE band of (PPA) 6 In 1– x Sb x Br 9 has nearly the same positions of the Sb 3+ absorption bands (Figure S7c). The asymmetric double excitation band at 365 and 380 nm corresponds to the A band, and the singlet excitation band at 324 nm corresponds to the B band.…”

Organic−inorganic metal halides (OIMHs) have various crystal structures and offer excellent semiconducting properties. Here, we report three novel OIMHs, (PPA) 6 InBr 9 (PPA = [C 6 H 5 (CH 2 ) 3 NH 3 ] + ), (PBA) 2 SbBr 5 , and (PBA) 2 SbI 6 (PBA = [C 6 H 5 (CH 2 ) 4 NH 3 ] + ), showing typical zero-dimensional (0D) structure, octahedra dimers, and corner-sharing one-dimensional chains and crystallized in the monoclinic system with P2 1 , P2 1 /c, and C2/c space groups, respectively. (PPA) 6 InBr 9 , (PBA) 2 SbBr 5 , and (PBA) 2 SbI 6 have experimental optical band gaps of ∼3.16, ∼2.24, and 1.48 eV, respectively. (PPA) 6 InBr 9 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 3+ 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) 6 InBr 9 stems from the isolated ns 2 luminescent center and strong electron−phonon coupling, making the spin-forbidden 3 P 1 − 1 S 0 observable. By combining commercial blue and green phosphors with orange-red-light-emitting (PPA) 6 In 0.99 Sb 0.01 Br 9 , 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 3+ shown to significantly enhance the luminescence properties, demonstrating their potential applications in solid-state lighting.

“…This means that the [InCl 6 ] octahedron is easily distorted, and the degree of distortion of the inorganic polyhedra in 0D OIMHs is closely related to STEs. 41 The degree of deformation of the pristine [InCl 6 ] 3− octahedron and the [InCl 6 ] 3− octahedron doped with 15% Sb can be calculated using eqn (1) and (2): 42 where Δ d is the variance of the bond length of In–Cl and σ 2 is the variance of the bond angle of Cl–In–Cl. These two parameters are usually used to evaluate the degree of polyhedron distortion.…”

The physicochemical characteristics of a zerodimensional (0D) hybrid organic−inorganic bismuth bromide templated by 2-bromoethylammonium cations (BEA) 3 BiBr 6 are investigated. Single-crystal X-ray diffraction data showed that the examined material crystallizes in a triclinic P1̅ structure at room temperature with organic cation partial disorder involving one of the three independent BEA + cation types. The (BEA) 3 BiBr 6 crystal undergoes a first-order structural phase transition during cooling (256 K) to the completely ordered low-temperature P1̅ phase. Upon heating, two structural transformations during heating occur at 342 and 371 K to the monoclinic P2/n phase. According to the X-ray diffraction data and vibrational studies, the high-temperature and intermediate phases exhibit the same pattern of structural disorder including two independent BEA + cations. The dielectric, thermal, and vibrational investigations confirmed that the observed phase transitions are essentially related to the thermal evolution of cation disorder; however, they also involve changes in hydrogen bonds, distortion of halogenobismuthate ions, and conformational changes of BEA + cations. Optical experiments showed that the investigated material has a wide-bandgap energy of 3.07 eV and generates blue light below ca. 165 K when excited at 375 nm. Furthermore, research indicates that bromination of organic cations could become a new and effective method to fine-tune the optoelectronic properties.
