Deep-red-emitting phosphors of Mn-activated tantalite for high-sensitivity lifetime thermometry and security films.

Herein, single monoclinic phase Mn-doped SrInTaO (SITO) phosphors were reported in terms of both luminescence behaviors and potential applications. The optimal Mn-doped SITO (0.3 mol%) exhibited a good color purity of 92.

Designing bifunctional platforms for LED devices and luminescence lifetime thermometers: a case of non-rare-earth Mn doped tantalate phosphors.

Non-rare-earth Mn doped tantalate (SrGdTaO) phosphors exhibiting deep-red emission were synthesized. Afterward, the phase structure, morphology, and optical properties (, emission spectra, concentration quenching, decay curves, thermal stability, quantum yields, .) were systematically investigated.

Regulating Dendrite-Free Zinc Deposition by Red Phosphorous-Derived Artificial Protective Layer for Zinc Metal Batteries.

Rational architecture design of the artificial protective layer on the zinc (Zn) anode surface is a promising strategy to achieve uniform Zn deposition and inhibit the uncontrolled growth of Zn dendrites. Herein, a red phosphorous-derived artificial protective layer combined with a conductive N-doped carbon framework is designed to achieve dendrite-free Zn deposition. The Zn-phosphorus (ZnP) solid solution alloy artificial protective layer is formed during Zn plating.

Recent Advanced Development of Artificial Interphase Engineering for Stable Sodium Metal Anodes.

A solid electrolyte interphase (SEI) on a sodium (Na) metal anode strongly affects the Na deposition morphology and the cycle life of Na metal batteries (SMBs). SMB applications are hindered by an unstable SEI and dendrite growth on the Na anode surface, which directly cause low coulombic efficiency and can even lead to safety issues. An artificial interface layer can stabilize Na metal anodes, be easily tailored, and is barely affected by electrochemical processes.

Room-temperature synthesis of near-ultraviolet light-excited Tb-doped NaBiF green-emitting nanoparticles for solid-state lighting.

We reported a facile reaction technique to prepare Tb-doped NaBiF green-emitting nanoparticles at room temperature. Under 378 nm excitation, the prepared samples exhibited the featured emissions of Tb ions and the green emission located at 543 nm corresponding to the D → F transition was observed in the photoluminescence (PL) emission spectra. The PL emission intensity relied on the dopant concentration and its optimum value was determined to be 50 mol%.
