Real‐Time Temperature Monitoring with Cr3+‐Based Hybrid Formate Perovskites: Insights into the Relation Between Chemical Composition and Thermometric Performance

open access: yesAdvanced Optical Materials, EarlyView.
Metal–organic frameworks with perovskite‐like structures show promising temperature‐dependent luminescence for thermometry. Our study explores [DMA]MII1‐xCrx(HCOO)3 compounds, revealing their potential for remote and time‐resolved temperature sensing.

Emerging Hydrochromic Metal Halide Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
Hydrochromic metal halide perovskites (MHPs) are promising candidates for next‐generation smart optical materials owing to their excellent responsiveness, superior reversibility, and highly tunable emission. This review summarizes the latest progress in hydrochromic MHPs and provides general principles for the rational design of advanced hydrochromic ...

A Type I Hyperbolic Metamaterial Driven by Phonons on ZnO

open access: yesAdvanced Optical Materials, EarlyView.
This article reports the first realization of a phonon‐driven type I hyperbolic metamaterial with ZnO/(Zn,Mg)O heterostructures. By adjusting the Mg content and layer thickness ratio, it establishes a clear framework for achieving and tuning the type I hyperbolic region via phonon resonances.

Bandgap Tuning of β‐(AlxGa1‐x)2O3 Nanosheets via Liquid Metal Interface Engineering

open access: yesAdvanced Optical Materials, EarlyView.
Ultrathin β‐(AlxGa1‐x)2O3 nanosheets with controlled composition are synthesized via low‐temperature squeeze‐printing of Al─Ga liquid alloys. Aluminium preferentially migrates to the surface of the liquid alloy, forming Al‐rich oxide layers with tunable bandgaps up to 6.4 eV. This compositionally precise approach enables the fabrication of 2D ultrawide‐

Pseudo‐Dichroism: Nanophotonic Induction of Chiroptical Activity in Symmetric Molecular Systems

open access: yesAdvanced Optical Materials, EarlyView.
By analyzing vibrational circular dichroism (VCD) spectra of chiral nanomaterials, we distinguish genuine molecular chirality (true dichroism) from measurement artifacts (pseudo dichroism) using a novel, robust framework. The spectral criteria we establish apply broadly to all chiroptical techniques in nanomaterial research, enhancing precision in ...
