Self‐Trapped Hole Migration and Defect‐Mediated Thermal Quenching of Luminescence in α‐ and ÎČ‐Ga2O3

open access: yesAdvanced Functional Materials, EarlyView.
Temperature‐dependent photoluminescence and first‐principles calculations reveal self‐trapped hole migration as the microscopic origin of thermal quenching in α‐ and ÎČ‐Ga2O3. The low migration barrier in α‐Ga2O3 enables defect trapping and enhances blue luminescence, while the higher barrier in ÎČ‐Ga2O3 preserves ultraviolet emission at elevated ...

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

open access: yesAdvanced Functional Materials, EarlyView.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...

Thermoplasmonic Nanorings for Passive Solar‐Responsive Smart Windows in Energy‐Efficient Building Applications

open access: yesAdvanced Functional Materials, EarlyView.
This work presents scalable silver nanorings with tunable thermoplasmonic properties for smart window applications. By responding to sunlight and environmental changes, the nanorings modulate near‐infrared light and reduce heat transmission. Their unique geometry enables dynamic optical control, offering a promising route toward energy‐efficient ...
