Abstract Aqueous zinc ion batteries are promising candidates for large‐scale energy storage. Nonetheless, the stability of Zn anodes in aqueous electrolytes is compromised by dendritic growth and undesirable side reactions. In this article, citrulline (Cit), a biocompatible compound, investigated as an electrolyte additive to achieve superior anodes. Experimental results theoretical calculations demonstrate that Cit, serving bifunctional additive, possesses abundant highly polar groups (─NH...
The presence of labile bulky insulating hydrocarbon ligands in halide perovskite nanocrystals (NCs) passivates surface traps but concurrently makes charge transport difficult optoelectronic devices. Early efforts routinely rely on the replacement long-chain with short-chain cousins, leading to notable changes NC's sizes and photophysical properties thus making it hard obtain devices nearly designed emissions. Here we report a general solution-phase ligand-exchange strategy produce...
Doping of semiconductors by introducing foreign atoms enables their widespread applications in microelectronics and optoelectronics. We show that this strategy can be applied to direct bandgap lead-halide perovskites, leading the realization ultrawide photoluminescence (PL) at new wavelengths enabled doping bismuth (Bi) into perovskites. Structural photophysical characterization reveals PL stems from one class Bi doping-induced optically active center, which is attributed distorted [PbI6]...
Cesium lead halide perovskite nanocrystals (NCs) have emerged as promising luminescent materials for a range of applications. However, the creation highly violet-emitting CsPbCl3 NCs mostly relies on doping limited number small-sized metal ions or post-synthetic surface treatment NCs. Alkaline-earth (AE) metals (e.g., Ca2+, Sr2+, and Ba2+) been proposed to be able substitute Pb2+ in perovskites, yet it remains incompletely understood whether AE can incorporated into lattice merely situated...
The synthesis of highly luminescent colloidal CsSnX3 (X = halogen) perovskite nanocrystals (NCs) remains a long-standing challenge due to the lack fundamental understanding how rationally suppress formation structural defects that significantly influence radiative carrier recombination processes. Here, we develop theory-guided, general synthetic concept for NCs. Guided by density functional theory calculations and molecular dynamics simulations, predict that, although there is an opposing...

Abstract Zinc halides have been less explored even though they are a promising lead‐free family with the merits of environmental friendliness and low cost. Here, organic–inorganic hybrid zinc screened aromatic molecules containing amino groups (MXDA: m‐Xylylenediamine, ABI: 2‐Aminobenzimidazole, pipda: 2‐piperidylmethylamine, p‐MPEA: p‐Methylphenethylamine), six new compounds discovered: (MXDA)ZnCl 4 ( 1 ), (ABI) 2 ZnCl (pipda) H OZnCl 3 [(pipda) Zn Br ]·H O (p‐MPEA) 5 ZnBr 6 ). The...
A novel violet-excitable Na 3 YSi 2 O 7 :Eu 2+ green phosphor for a high-quality white LED was developed via salt-flux assistance.
Ce3+, Eu2+ and Eu3+ singly activated Ce3+/Eu2+/Eu3+-coactivated Ca11(SiO4)4(BO3)2 (CSB) phosphors were synthesized by novel efficient aluminium reduction solid state reactions. Under ultraviolet light excitation, the CSB exhibit intense red, green blue emissions, respectively. The unique host shows its superior advantages in color balance compared with widely-used Ca2SiO4, Ca3B2O6 Y3Al5O12. colors can be controlled temperature, a white emitting phosphor was obtained reducing as-prepared...
Cesium lead halide (CsPbX3 (X = Cl, Br, I)) perovskite nanocrystals (NCs) have shown excellent prospects in lighting, display, and lasing fields owing to their photoluminescence (PL) properties. To dope rare earth ions into perovskite, CsPbX3 I) NC hosts not only inherit the narrow linewidth excitonic properties but also yield unique emission. Herein, engineering of such luminescence is achieved for Eu3+-doped CsPbCl3–xBrx (x 0, 1, 1.5, 2, 3) solid solution NCs first time. The singly doped...
Abstract Recently, all‐inorganic halide perovskite (CsPb X 3 , ( = Cl, Br, and I)) nanocrystals (NCs) based hybrid architectures have attracted extensive attention owing to their distinct luminescence characteristics. However, due stress lattice mismatch, it is still a challenge construct heterojunctions between NCs the nanostructures with different parameters non‐cubic contour.

A novel Eu 2+ activated oxonitridosilicate cyan phosphor for enhancing the color quality of a violet-chip-based white LED was developed.
The metal halides have superior optoelectronic properties because of their special electronic structures, such as the ns2 (Pb2+, Sb3+, Sn2+, etc.) and dx (Zn2+, Cd2+, Mn2+,...
