Monotonous luminescence has always been a major factor limiting the application of organic room-temperature phosphorescence (RTP) materials. Enhancing and regulating intermolecular interactions between host guest is an effective strategy to achieve excellent performance. In this study, halogen bonding (CN⋅⋅⋅Br) was introduced into host-guest RTP system. The interaction promoted intersystem crossing stabilized triplet excitons, thus helping strong emission. addition, weak sensitive external...
The low efficiency triplet emission of hybrid copper(I) iodide clusters is a critical obstacle to their further practical optoelectronic application. Herein, we present an efficient cluster emitter (DBA)4 Cu4 I4 , where the cooperation excited state structure reorganization and metallophilicity interaction enables ultra-bright yellow-orange with photoluminescence quantum yield over 94.9 %, phonon-assisted de-trapping process exciton induces negative thermal quenching effect at 80-300 K. We...
Abstract Lead‐based halide perovskite nanomaterials with excellent optical properties have aroused great attention in the fields of solar cells, light‐emitting diodes, lasing, X‐ray imaging, etc. However, toxicity lead prompts researchers to develop alternatives cut down usage lead. Herein, all‐inorganic manganese‐based derivatives, CsMnCl 3 nanocrystals (NCs), uniform size and morphology been synthesized successfully via a modified hot‐injection method. These NCs direct bandgap 4.08 eV...
A carbon quantum dot (CQDs)/Ag3PO4/BiPO4 heterostructure photocatalyst was constructed by a simple hydrothermal synthesis method. The as-prepared CQDs/Ag3PO4/BiPO4 has been characterized in detail X-ray diffraction, field-emission scanning electron microscopy, transmission photoelectron spectroscopy, ultraviolet–visible and photoelectrochemical measurements. It is demonstrated that the composite assembling Ag3PO4 fine particles CQDs on surface of rice-like BiPO4 granules. exhibits higher...
Abstract Lead‐halide perovskites have received extensive attention in X‐ray imaging applications recently. However, their poor stability, lead toxicity, and strong light self‐absorption seriously limit the commercial development. Here, we report a vacancy‐ordered Cs 2 HfCl 6 double perovskite for scintillators applications. The microcrystals (MCs) are characterized by broadband blue emission with large Stokes shift. Joined experimental‐theoretical characterizations reveal highly localized...

Effect of Sn on the corrosion properties a homogenized Mg-6Zn-0.25Ca alloy was investigated. The resistance ZX60 and ZXT601 alloys analyzed using XRD, metallography, SEM, mass loss, hydrogen evolution, electrochemical polarization curve impedance spectrum. results indicate that Mg-6Zn-Sn-0.25Ca is mainly composed CaMgSn MgZn2 phases. After an addition Sn, grains are significantly refined, volume fraction second phase with disperse distribution increases. precipitates as well. can improve...
