Vibronically Coupled and Thermally Tunable Broadband NIR Optical Response in 0D W4+‐Activated Cs2ZrCl6 Perovskite for Multifunctional NIR Spectroscopy Applications

open access: yesAdvanced Science, EarlyView.
A vibronic coupling‐assisted way is provided for circumventing thermal quenching related to transient lattice distortion in 0D halide perovskites, and this study offers comprehending electron–lattice interactions in low‐dimensional host–W4+ dopant systems for the development of thermally tunable NIR spectroscopy applications, such as HF gas sensing and

High‐Temperature Single‐Photon Emission From Covalently Functionalized van der Waals Heterostructures

open access: yesAdvanced Science, EarlyView.
Covalent diazonium functionalization of graphite‐WSe2 heterostructures produces high‐purity single‐photon emission from WSe2 at T = 90 K, far above the typical T = 10 K limit. The chemical modification reshapes graphite's electronic structure and couples to WSe2 midgap states, stabilizing quantum emitters at elevated temperatures and opening pathways ...

Self‐Assembled Monolayers Facilitate Simultaneous Enhancements of External Quantum Efficiencies and Circularly Polarized Luminescence Dissymmetry Factors for Chiral Perovskite Red Spin‐Light Emitting Diodes

open access: yesAdvanced Science, EarlyView.
With the self‐assembled monolayer (SAM), external quantum efficiencies and dissymmetry factors for circularly polarized electroluminescence are simultaneously enhanced for chiral perovskite red spin‐light emitting diodes (spin‐LEDs). These are ascribed to the improvements of magneto‐chiroptical and electronic properties.

A Biomimetic Fiber‐Entangled Permeable Electronic Skin for Strain‐Insensitive and High‐Resolution Tactile Sensing

open access: yesAdvanced Science, EarlyView.
A biomimetic fiber‐entangled island architecture is proposed to address the stress concentration issues commonly observed in conventional island arrays. Based on this architecture, a pressure‐sensing e‐skin with simultaneously high spatial resolution, low strain interference, and excellent permeability is developed, which is further applied to wearable
