Near‐Field Nanoimaging of Programmable Phase Transitions in Ga+‐Irradiated VO2

open access: yesAdvanced Optical Materials, EarlyView.
Focused Ga+ ion irradiation locally reprograms the insulator‐to‐metal transition in VO2 thin films. Infrared and terahertz near‐field nanoimaging reveals that low irradiation doses localize the resistive‐switching filament within the defect region, while high doses suppress switching there and redirect the filament into pristine VO2.

Helium Ion‐Induced Degradation Mechanisms in Optical Coatings for Space Applications

open access: yesAdvanced Optical Materials, EarlyView.
Although low‐energy helium ions represent a significant source of degradation for optical coatings operating in space environments, their effects remain poorly understood. Systematic irradiation of over 150 metal and dielectric thin‐film samples at 4, 16, and 100 keV investigates the damage mechanisms and their impact on optical performance ...

Facile, Scalable, and High‐Yield Synthesis of a Near‐Unity Quantum Yield Zero‐Dimensional Copper Halide Cs3Cu2Cl5 Scintillator for X‐Ray Imaging

open access: yesAdvanced Optical Materials, EarlyView.
A dioxolane‐mediated reaction synthesis provides a simple and scalable route to phase‐pure Cs3Cu2Cl5 scintillator powders with near‐complete conversion, near‐unity photoluminescence quantum yield, and long‐term stability. The resulting green‐emitting composite films exhibit strong radioluminescence, high light yield, and practical compatibility with ...
