A series of Bi<sup>3+</sup>-doped garnet-based UVB persistent phosphors have been developed, which can be conveniently charged by either a standard 254 nm lamp or natural sunlight, producing light emission peaking at 313 nm.
Bi<sub>2</sub>SiO<sub>5</sub>:Yb<sup>3+</sup>,Er<sup>3+</sup> yolk–shell nanophosphors have been successfully synthesized, which are expected to find important applications in optical thermometry and solid-state lighting.
An NIR-emitting MgGeO 3 :Mn 2+ ,Yb 3+ persistent phosphor chargeable with red light has been developed. The features of red-light charging and NIR luminescence make this hold great potential for biomedical imaging optical data storage.
CO<sub>2</sub> hydrogenation towards COOH is more favorable on perfect CeO<sub>2</sub> (111) surface, whereas reductive dissociation of predominant O-defective surface. The O vacancy promotes
Luminescent materials that emit in the narrowband ultraviolet-B (NB-UVB; 310-313 nm) spectral region have attracted considerable attention due to their unique features, which endow them with great potential applications fields of photochemistry and photomedicine. However, NB-UVB persistent luminescent are relatively lacking, especially excitable by natural sunlight. Here we report luminescence Gd3+ (Y,Gd)3Ga5O12:Bi3+ garnets making use energy transfer from Bi3+ Gd3+. The optimal...
The alloying element Sn plays bifunctional and ligand effect roles to strengthen the O-end species adsorptions, adjust electronic structures, weaken Pt–CO bonds, thus enhance CO tolerance of Pt<sub>3</sub>Sn(111).
Core-shell Bi2SiO5 nanosystem with uniform morphology and narrow size distribution has been successfully synthesized via a facile template-assisted route. With the introduction of Eu3+, detailed studies are performed to evaluate its promise as Eu3+-based phosphor host. The yielded Bi2SiO5:Eu3+ nanospheres proven be pure tetragonal phase X-ray diffraction Rietveld refinement. Moreover, particles consist monodisperse spheres an average diameter approximately 285 nm...
Fragment velocity is a crucial parameter for evaluating the destructive capability of warhead, and it typically calculated using Gurney formula with corrections.The currently established correction formulas can determine axial distribution natural fragment within shell, but preformed fragmentation energy losses due to existence gaps lead results that are larger than actual values, making unsuitable accurate calculation in such warheads.This paper introduces filling ratio function based on...
Cadmium based chalcogenides quantum dots exhibited ultrahigh photoluminescence, yields and multicolor luminescence.
Al-4 wt.%Ni (hypoeutectic), Al-5.69 (eutectic) and Al-8 (hypereutectic) liquid alloys are highly undercooled rapidly solidified under free fall condition. Theoretical calculations indicate that the coupled zone of (Al+Al3 Ni) fibrous eutectic is an unclosed region in composition range from 4.8 to 15 wt.% Ni, which strongly skewed towards Al3 Ni phase side. It found cooling rate undercooling would increase as droplet size decreases. Then microstructural evolution Al-Ni will be induced by...
Rare earth (RE3+)-doped NaY(MoO4)2 nanocrystals are efficient materials for realizing multicolor emission, which plays an important role in displays, W-LEDs, solar cells and biolabeling. Up to now, research on the tuning properties of RE3+-doped nanoparticles has mostly focused traditional preparation routes such as hydrothermal method sol-gel process. However, products obtained using these methods usually large size (on micron/submicron scale) agglomeration problems inevitable. With...
The solidification characteristics of three types Pb-Sb-Sn ternary alloys with different primary phases were studied under substantial undercooling conditions. experimental results show that (Pb) and SbSn grow in the dendritic mode, whereas (Sb) phase exhibits faceted growth form polygonal blocks long strips. solid solution displays strong affinity intermetallic compound so they produce various morphologies pseudobinary eutectics, but it can only divorced eutectic mode together phase....
