Abstract Owing to their unique optical, electronic, and catalytic properties, metal nitrides nanostructures are widely used in optoelectronics, clean energy, catalysis fields. Despite great progress has been achieved, synthesis of defect‐rich (DR) bimetallic nitride nanocrystals or related nanohybrids remains a challenge, electrocatalytic application for oxygen evolution reaction (OER) not fully studied. Herein, the DR‐Ni 3 FeN N‐doped graphene (N‐G) (DR‐Ni FeN/N‐G) fabricated through...
Water-soluble, fluorescent carbon dots (CDs) have been successfully synthesized from waste paper. The as-prepared CDs, with an amorphous structure and small particle size, exhibit good photostability, high photoluminescence quantum yields (PLQYs) fairly low toxicity, which indicate potential applications in the field of biolabelling.
A series of composites nanocrystalline TiO2 with exposed {001} facets and high quality graphene sheets (GS) were synthesized via a one-step hydrothermal reaction in an ethanol–water solvent. The obtained facets-exposed TiO2/GS photocatalysts characterized by Raman spectroscopy (RS), X-ray photoelectron (XPS), diffraction pattern (XRD), field emission scanning electron microscopy (SEM), transmission (TEM), ultraviolet visible (UV-vis) diffuse reflectance (DRS) Electrical Impedance...
Functional traits and their variation mediate plant species coexistence spatial distribution. Yet, how patterns of in belowground influence resource acquisition across communities remains obscure. To characterize diverse strategies relation to abundance, we assessed four key - root diameter, branching intensity, first-order length mycorrhizal colonization 27 coexisting from three grassland along a precipitation gradient. Species with thinner roots had higher but shorter consistently low...
Inorganic photochromic material is an available medium to obtain optical information storage. The property of the inorganic mainly from defects host. However, formation in host uncontrollable, particular, revisable and removement are difficult. Thus, there few materials with photochromism upon entire light stimulation. Therefore, it urgent need find a suitable approach design materials. Here, PbWO4:Yb3+, Er3+ ceramic was designed help valence state change W6+ → W5+ Pb2+ Pb4+. Upon 532 nm...
Abstract Broadband near‐infrared (NIR) luminescent materials have received notable attention due to their distinct photophysical properties for designing NIR light‐emitting diodes (NIR LEDs). Here, a series of Ca 3− x Lu Ga 2+ Ge O 12 :Cr 3+ (CLGGG:Cr ) ( = 0–1) NIR‐emitting garnet phosphors with an emission range 660–1200 nm are successfully developed and lattice parameters structurally analyzed. Upon 460 blue light excitation, the exhibit both substantial spectral broadening (FWHM: 129→267...
Halide perovskite has been widely studied as a new generation of photoelectronic materials. However, their thermal and humidity-induced emission quenching have greatly limited utility reliability. Here, we report hexagonal Mn2+ -doped CsCdCl3 crystal that possesses stable photoluminescence (PL) at both high temperature humidity. The room long-persistent luminescence (LPL) the single crystals lasts up to 1480 s can be adjusted by changing concentration ion doping. characteristic d-d...
In recent years, novel metal halide scintillators have shown great application potential due to their tunable emission wavelength, high X-ray absorption, and luminescence efficiency. However, poor stability complex device packaging remain key issues for scintillators, making it difficult achieve high-resolution flexible imaging applications. To address the above issues, a multiprocessing strategy was introduced prepare Cs3Cu2I5@PMMA scintillator films long-term stable application, mainly...

The luminescence properties Mn2+ singly doped co-doped with Ce3+ into YAG host discussed. It is observed that in sample, ions not only occupy two kinds Al3+ sites to generate a yellow deep red emission bands, but also Y3+ obtain green band host. Considering substitution Al3+, quadrivalence including Zr4+, Ge4+ Si4+ are...
Anatase/rutile mixed titania nanotubes (TiO2 NTs) precipitated with gold nanoparticles (Au NPs), i.e. Au/TiO2, have been synthesized and investigated on visible photocatalysis properties.
