Energy Transfer from Pr to Gd and Upconversion Photoluminescence Properties of YOF:Pr, Gd.

Upconversion materials have numerous potential applications in light energy utilization due to their unique optical properties. The use of visible light excitation to obtain ultraviolet emission is a promising technology with broad application prospects, while relevant research is absent. A series of Pr, Gd doped YOF phosphors were synthesized by traditional solid-state reaction.

Enhanced Hydrogen Evolution Reactivity of T'-Phase Tungsten Dichalcogenides (WS, WSe, and WTe) Materials: A DFT Study.

The hydrogen evolution reaction (HER) plays a crucial role in hydrogen gas production. Layers of transition-metal dichalcogenides (TMDs) possess adjustable electronic structures, and TMDs with H-phase structures have been proposed as substitute HER catalysts. Nonetheless, there are few systematic theoretical analyses of the HER catalytic properties of TMDs with T'-phase structures.

Room temperature synthesis of CdS/SrTiO nanodots-on-nanocubes for efficient photocatalytic H evolution from water.

Spontaneous solar-driven water splitting to generate H with no pollution discharge is an ideal H generation approach. However, its efficiency remains far from real application owing to the poor light-harvesting and ultrafast charge recombination of photocatalysts. To address these issues, herein, we employed a novel but simple chemical bath deposition (CBD) method to construct CdS/SrTiO nanodots-on-nanocubes at room temperature (ca.
