Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

Advanced Materials, EarlyView.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

How the Arrangement of Platinum Atoms on Ruthenium Nanoparticles Improves Hydrogen Evolution Activity

Advanced Materials, EarlyView.
A synthetic strategy for the formation of Pt islands and their transformation into Pt atomic strings on Ru nanoparticle surfaces is presented. The thermodynamically favored configuration of Pt strings on Ru catalyst is demonstrated to catalyze HER via the faster Volmer–Tafel pathway with a significantly improved intrinsic activity, owing to the well ...

Magnetocrystalline Anisotropic Platinum–Palladium–Iron Ternary Intermetallic Alloy for Enhanced Fuel Cell Electrocatalysis

Advanced Materials, EarlyView.
In this study, how crystallographic anisotropy governs the catalytic process is investigated by comparing the tetragonal L10 and cubic L12 ordered phases in a newly developed PtPdFe ternary intermetallic system. New insights into the fundamental understanding of the ordered Pt‐based ternary intermetallic alloys are introduced, unveiling ...

High‐Precision 3D Doping of Fused Silica Glass Derived from Nanocomposites

Advanced Materials, EarlyView.
The local integration of dopants enables the selective modification of color, luminescence or refractive index within a three‐dimensionally shaped glass with micron resolution. Following the fabrication of porous glass preforms and infusion with a dopant mixture, the dopant is immobilized by lithographic techniques and subsequently debinded and ...
