The 3D-structure-mediated growth of zero-dimensional Cs₄SnX₆ nanocrystals

Abstract

The innovation of approach to synthesize high quality lead perovskite nanocrystals enable prosperous development of nanocrystal based optoelectronic devices in recent years. However, the transfer of this approach to tin...

Manipulating the sublattice distortion induced by Mn2+doping for boosting the emission characteristics of self-trapped excitons in Cs4SnBr6

“…To the best of our knowledge, this is the highest value obtained for Cs 4 SnBr 6 (Table S1, ESI †). [9][10][11][12][13][14] With an increasing doping level, the PL band of sample S-1 is broadened with a small shoulder appearing B590 nm, leading to the change in the emission color (see Fig. 1(a)).…”

“…[5][6][7][8] Among them, 0D tin halide perovskites (Cs 4 SnX 6 , X = Br and I) emerged as promising materials for environmental friendly phosphors with high PL QYs because of their similar electronic structures to those of lead halide perovskites. [9][10][11][12][13][14] Kovalenko's group reported fully inorganic 0D Cs 4 SnBr 6 showing strong green emission from STEs with a PL QY of 15% AE 5%. 10 Unfortunately, the stability of Cs 4 SnBr 6 is influenced by the oxidation of Sn 2+ , limiting its practical applications.…”

Self‐assembly Behavior of Metal Halide Perovskite Nanocrystals

“…On the other hand, the absence of ligands may lead to the aggregation of NCs. [ 53 ] (3) As for the dispersion, the polarity plays a significant role in attaining superlattices. Using single solvent may not be the best choice while we are more likely to prepare targeted self‐assembled configurations by precisely controlling the polarity of mixing solvents.…”

Healthy and stable lighting via single-component white perovskite nanoplates

“…Currently, there are two types of single-component white LHP materials. (1) Self-trapped LHP materials always exhibited broad-band warm-white emission with inevitable deep blue light emission and unalterable color temperature, 18,19,[33][34][35][36][37] which are mainly due to the poor bandgap tunability of selftrapped LHPs. It should be noted that the color temperature is also quite important for applying the light source in different situations.…”
