Peroxide‐Assisted Solvate Engineering Enables Record‐High Birefringence in a Solar‐Blind Transparent Crystal

open access: yesAngewandte Chemie, EarlyView.
H2O2‐directed solvate engineering reorganizes ∞[4HP] (4‐hydroxypyridine) chains from a crossed arrangement into a nearly parallel packing through strengthened hydrogen‐bonding interactions. The resulting peroxide‐containing crystal, 4HP·H2O2, exhibits a solar‐blind UV cutoff edge (278 nm) and giant birefringence (0.609 @ 546 nm). This work demonstrates

Tuning the Plasmonic Resonance Peak for Al Nanorods on AlGaN Layer to Deep Ultraviolet Band

open access: yesIEEE Photonics Journal, 2021
Tuning the plasmonic resonance peak to the deep ultraviolet (DUV) band is critical for plasmonic-enhanced AlGaN-based DUV photodetector. However,the high refractive index of AlGaN layer seriously limits the plasmonic resonance peak in DUV band. Therefore,
