High Efficiency NIR Luminescence Beyond 900 nm Through Promoting Cr3+ Pair Generation in Sr3Zr2O7 Layered Perovskite

open access: yesLaser &Photonics Reviews, EarlyView.
A Cr3+/La3+ codoped Sr3Zr2O7 NIR phosphor showing luminescence at ∼960 nm with high IQE/EQE (92.4%/57.5%) and good thermal stability was developed. La3+ stabilizes Cr3+ and induces Cr3+ pairs, enabling efficient blue‐to‐NIR conversion for underwater wireless optical communication.

Truncated Octahedral PtCu Alloy Nanoparticles for Efficient Methanol Electrooxidation

open access: yesMetalMat, EarlyView.
Platinum–copper nano‐truncated octahedra are developed as efficient electrocatalysts for methanol oxidation in alkaline media, exhibiting notably enhanced activity compared to commercial Pt/C. Experimental and theoretical analysis reveals that alloying with copper modifies the electronic structure of platinum, facilitating the key reaction step and ...

Asymptotics for the Spectrum of the Laplacian in Thin Bars with Varying Cross Sections

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We consider spectral problems for the Laplace operator in 3D rod structures with a small cross section of diameter O(ε)$$ O\left(\varepsilon \right) $$, ε$$ \varepsilon $$ being a positive parameter. The boundary conditions are Dirichlet (Neumann, respectively) on the bases of this structure, and Neumann on the lateral boundary.
