Zinc germanate doped with Mn2+ (Zn2GeO4:Mn2+) is known to be a persistent luminescence green phosphor potential applications in biosensing and bioimaging. Such demand nanoparticulated phosphors uniform shape size, good dispersibility aqueous media, high chemical stability, surface-functionalization. These characteristics could major bottlenecks hence limit their practical applications. This work describes one-pot, microwave-assisted hydrothermal method synthesize highly Zn2GeO4:Mn2+...
We have synthesized Eu-doped NaBi(MoO 4 ) 2 nanoparticles functionalized with PAA whose properties make them excellent multimodal contrast agents for X-ray computed tomography and luminescent bioimaging, as illustrated using a C. Elegans animal model.
We report on a novel synthesis method, which produces NaY(MoO4)2 nanoparticles having an almost spherical shape and hydrophilic character. The procedure is also suitable for the preparation of NaY(MoO4)2-based nanophosphors by doping this host with lanthanide cations (Eu3+, Tb3+ Dy3+), which, under UV illumination, exhibit intense luminescence whose color determined selected cation (red Eu3+, green yellow Dy3+). effects level luminescent properties are analyzed in terms emission intensities...
The synthesis of uniform neodymium-doped lanthanum trifluoride nanoparticles with lenticular shape and a mean diameter around 45 nm by using homogeneous precipitation method is reported. luminescent properties the synthesized samples in terms their emission spectra lifetime are analyzed as function Nd content to find optimum phosphor its suitability for imaging second biological window. X-ray attenuation evaluated investigate additional ability contrast agent computed tomography. Finally,...

Abstract The improvement of many applications in the fields catalysis, surface and coatings technology, biomedicine, fuel cells depends on advances nanoalloy research. Here, a structural thermal study nanostructures Cu–Ta particles produced using high‐current pulsed arc (HCPA) is presented. Structural analysis performed utilizing electron microscopy X‐ray spectroscopy shows formation distinctive single crystals with grain sizes larger than 100 nm. Notably, these grains exhibit evidence...
The instant at which a high-current pulsed arc evaporates Cu and Ta wires is illustrated. This method creates interesting oxygen-free Cu–Ta powder having high-temperature stability, high oxidation temperature, single-crystals showing compatible evidence of exceptional miscibility. More details can be found in article number 2000921 by Rafael Mendoza-Pérez, Amin Bahrami, co-workers.
The sputtering yield amplification (SYA) is a phenomenon based on doping target with atoms of higher atomic mass. This changes the depth and direction collision cascade in surface promoting ejection atoms. In this work, we present new way generating SYA without need expensive complex deposition systems. was accomplished by increasing working pressure adding small pieces W, as dopant element, racetrack Si target. physical phenomena necessary to promote SYA, for our experimental parameters,...
