Hybrid hydrogels based on electrostatic co-assembly of polyoxometalates and ABA triblock copolymers were readily prepared and exhibit excellent luminescence and self-healing performance.

Alternations of crystalline and amorphous states largely influence the solid-state properties molecular materials. In their Research Article (e202217054), Dongpeng Yan co-workers show that transformation between two an anthracene-based metal-organic complex can tune photosalient effect, mechanical luminescence, photochromism behavior. The effect was assigned to competitive chemical routes a pho...

Objective(s): This paper describes synthesisPolyvinyl Alcohol/CaF2:Er nanofibers because of  its  photoluminescence properties.Materials and Methods:  First, CaF2:Er nanocomposite synthesized with co-precipitation method. In order to prepare polyvinyl alcohol (PVA)/CaF2:Er nanofibers, CaF2:Er nanocomposites were added to the polyvinyl alcohol (PVA) polymer. PVA/CaF2:Er composite nanofibers were...

Enhancement of upconversion luminescence is imperative for the applications of upconversion nanocrystals (UCNs). In this work, we investigated the upconversion luminescence enhancement of NaYF4:Yb/Er by Mo(3+) ion doping. It was found that the upconversion luminescence intensities of the green and red emissions of UCNs co-doped with 10 mol% Mo(3+) ions were enhanced by 6 and 8 times, respective...

Application of Long-Persistent Luminescence Materials In article number 2207331 by Zhifeng Shi and co-workers, a novel metal-halide single crystal inorganic cesium cadmium chlorine (CsCdCl3) is reported, which displays long-persistent luminescence with long duration 6000 s. The diagram above vividly depicts that the inherent defects CsCdCl3 crystals act as energy traps to trap store electrons, ...

Nano-sized particles of monoclinic-LaVO4 were prepared in a short reaction time of 30 minutes by employing a microwave assisted hydrothermal synthesis in the presence of glycerol, which was used both as a solvent and structure-directing agent. The tetragonal-LaVO4 is known to show strong luminescence properties when doped with Ln(3+), whereas the monoclinic-LaVO4 is usually considered not suita...

Although the application of biodegradative genetically engineered micro organisms (GEMs) for bioremediation is very promising, the risks of their release should be assessed before their introduction into the environment. Lux-marked Ralstonia eutropha H850Lr (formerly Alcaligenes eutrophus H850Lr) was introduced into sterile and non-sterile soil microcosms at matric potentials ?2.11, ?30, ?750, ...

The up-conversion luminescence of Zn1−xMgxS:Mn 2+ nanoparticles fabricated by an inorganic precipitation method is studied by using a near-infrared femtosecond laser. The up-converted luminescence is blueshifted when increasing the Mg composition because of weaker crystal field effect. Comparing with thin films, the luminescence of Zn1−xMgxS:Mn 2+ nanoparticles shifts several nanometers to the ...
