Low-dimensional organic–inorganic metal halide hybrids (OIMHs) with an ultrabroad-band emission are promising as downconversion phosphors for solid-state lighting. However, toxicity of Pb and low photoluminescence quantum efficiency (PLQE) hamper their application. Herein, two zero-dimensional (0D) lead-free organic antimony (Sb) chloride (Cl) dual-band emissions PLQEs: (TTA)2SbCl5 (TTA = tetraethylammonium) (TEBA)2SbCl5 (TEBA benzyltriethylammonium) reported. Both compounds show a single...
Low-dimensional metal halide hybrids (OIMHs) have recently been explored as single-component white-light emitters for use in solid-state lighting. However, it still remains challenging to realize tunable emission lead-free zero-dimensional (0D) hybrid system. Here, a combination strategy has proposed through doping Sb3+ enabling and balancing multiple centers toward the multiband warm white light. We first synthesized new 0D (C8NH12)6InBr9·H2O single crystal, which isolated [InBr6]3-...
Modeling and prediction of forest fire occurrence play a key role in guiding prevention. From the perspective whole world, fires are natural disaster with great degree hazard, many countries have taken mountain as an important measure for prevention control, conducted corresponding research. In this study, model based on LSTNet is proposed to improve accuracy forecasts. The factors that influence obtained through remote sensing satellites GIS, their correlation estimated using Pearson...
The frequent occurrence of forest fires causes irreparable damage to the environment and economy. Therefore, accurate detection is particularly important. Due various shapes textures flames large variation in target scales, traditional fire methods have high false alarm rates poor adaptability, which results severe limitations. To address problem low accuracy caused by multi-scale characteristics changeable morphology fires, this paper proposes YOLOv5s-CCAB, an improved model based on...
Abstract Broadband near‐infrared (NIR) emissions in the long wavelength region with simultaneous high efficiency and thermal stability are desirable for NIR phosphor‐converted light‐emitting diodes (NIR pc‐LEDs) light sources. Herein, a novel broadband NIR‐emitting phosphor is reported, Ba 5 La 3 MgAl O 15 :Cr 3+ (BLMAO:Cr ), which exhibits emission band spanning 700–1300 nm maximum peak ( λ max ) at 925 full width half of 160 nm. The optimized achieves an internal quantum 66%, integrated...
Broadband near-infrared (NIR) luminescent materials hold the key to next-generation, smart, NIR light sources.

Achieving axially chiral biaryl dialdehydes through asymmetric catalysis remains significantly challenging due to the lack of efficient strategies. In this report, we developed a rhodium‐catalyzed enantioselective C−H amidation transient directing group strategy. With new approach, series amido were achieved in up 86% yields with 99.5:0.5 er. Furthermore, detailed mechanistic studies indicated that both imine formation and bond cleavage steps reversible. More interestingly, X‐ray...

Multicolor luminescent materials hold great potential in high-level optical anticounterfeiting and encryption technologies. However, achieving multiple luminescence a single phosphor with dopant, especially covering visible invisible regions simultaneously, remains standing challenge. Herein, we successfully realize dual-band emission single-doped γ-AlON:Mn2+ phosphors.
