Low-dimensional metal halides have recently attracted extensive attention owing to their unique structure and photoelectric properties. Herein, we report the colloidal synthesis of all-inorganic low-dimensional cesium copper halide nanocrystals (NCs) by adopting a hot-injection approach. Using same reactants ligands, but different reaction temperatures, both 1D CsCu2 I3 nanorods 0D Cs3 Cu2 I5 NCs can be prepared. Density functional theory indicates that reduced dimensionality in compared...
All-inorganic colloidal perovskite quantum dots (QDs) based on cesium, lead, and halide have recently emerged as promising light emitting materials. CsPbBr3 QDs also been demonstrated stable two-photon-pumped lasing medium. However, the reported two photon absorption (TPA) cross sections for these differ by an order of magnitude. Here we present in-depth study TPA properties with mean size ranging from 4.6 to 11.4 nm. By using femtosecond transient (TA) spectroscopy found that section is...
Abstract All‐inorganic zero‐dimensional (0D) metal halides have recently received increasing attention due to their excellent photoluminescence (PL) performance and high stability.

Recently, two-dimensional organic–inorganic perovskites have attracted increasing attention due to their unique photophysical properties and high stability. Here we report a lead-free, perovskite, (PEA)2GeI4 (PEA = C6H5(CH2)2NH3+). Structural characterization demonstrated that this 2D perovskite structure is formed with inorganic germanium iodide planes separated by organic PEAI layers. has direct band gap of 2.12 eV, in agreement 2.17 eV obtained density functional theory (DFT)...
Hybrid two-dimensional (2D) organic–inorganic perovskites continue to draw increased attention in view of their outstanding performance optoelectronic devices such as solar cells and light-emitting devices. Herein, for the first time, we report synthesis characterization lead-free, 2D mixed Ge–Sn halide perovskites, (PEA)2Ge1–xSnxI4 (where PEA = C6H5CH2CH2NH3+), demonstrate that bandgaps decrease linearly with increasing Sn content. Most importantly, among them, (PEA)2Ge0.5Sn0.5I4 possesses...

Metal halide perovskites have attracted extensive attention in the field of photocatalysis, because their excellent photophysical properties, including high optical absorption coefficients, tunable band structures, and long carrier diffusion lengths. The application prospect conventional lead-based is restricted by toxicity instability issues. Therefore, it imperative to develop environmentally friendly stable lead-free (LFHPs) for photocatalysis. In recent years, rapid development LFHPs has...
Abstract All‐inorganic metal halides with afterglow emission have attracted increasing attention due to their significantly longer duration and higher stability compared organic–inorganic hybrid counterparts.

Zero-dimensional metal halides have emerged a versatile platform for the development of light-emitting materials, but achieving tunable or even multicolor emission from material containing single type has proven highly challenging. Here, we leverage “structural tolerance” recently-developed polymeric to integrate two distinct coordination units into material, thereby optical properties in single-phase halides. By manipulating steric hindrance polycations, facilely adjustable green, red...
