A promising 1D Cd-based hybrid perovskite-type for white-light emission with high-color-rendering index

Abstract

The synthesized 1D-perovskite-type (C6H7NBr)3[CdBr5] shows a broad-band white light emission with an extra-high CRI of 98 and chromaticity coordinates (0.30, 0.32).

Structurally Dimensional Engineering in Perovskite Photovoltaics

“…At the same time, it can be seen from the state density analysis that the VBM of the material originated from the combination of Br‐4p orbitals and Cd‐4d orbitals, while CBM originated from Cd‐5s orbitals. [ 62 ] Hu et al. synthesized 1D perovskite, (R)‐(−)‐1‐cyclohexylethylammonium/(S)‐(+)‐1 cyclohexylethylammonium) PbI 3 , and performed DFT calculations, and the bandgap of the predicted perovskite was in good agreement with the absorbance curve of the experimental results.…”

“…At the same time, it can be seen from the state density analysis that the VBM of the material originated from the combination of Br-4p orbitals and Cd-4d orbitals, while CBM originated from Cd-5s orbitals. [62] Hu et al synthesized 1D perovskite, (R)-(−)-1-cyclohexylethylammonium/(S)-(+)-1 cyclohexylethylammonium) PbI 3 , and performed DFT calculations, and the bandgap of the predicted perovskite was in good agreement with the absorbance curve of the experimental results. [63] According to the concept of electronic dimensionality, the 1D halide perovskite adopts the 1D electronic dimensionality without the octahedral distortion; however, if the distortion exists, the electronic dimensionality is lowered to <1D.…”

Assembly of a cadmium(ii)-based chiral complex: crystal structure and optical properties for solid state white-light emission applications

“…Therefore, the main optical absorption of this Compound below 310 nm mainly derives from the electron transitions of C-HÁ Á Áp within the organic cations, which is similar to some hybrid compound containing conjugated organic cations. 55…”

Crystal structure, optical characterization, conduction and relaxation mechanisms of a new hybrid compound (C6H9N2)2[Sb2Cl8]

“…[13][14][15] In comparison to the organic or inorganic components alone, these hybrids have excellent structural, optical, and electrical characteristics. [16][17][18][19] Here, for the rst time, we synthesized (C 6 H 9 N 2 ) 2 [Sb 2 Cl 8 ] single crystals via slow solvent evaporation. We performed a series of characterizations using single-crystal X-ray diffraction, Scanning electronic microscopy (SEM), ultraviolet-visible (UV-vis) spectroscopy, and complex impedance spectroscopy.…”
