Supraballs Composed of Mie‐Resonant Silicon Nanospheres

open access: yesAdvanced Optical Materials, EarlyView.
Spherical supraballs composed of Mie‐resonant silicon nanospheres are developed through an emulsion‐templated self‐assembly process. By systematically varying constituent silicon nanosphere size and interparticle spacing—both statically through oxidation and dynamically using thermoresponsive shells—the reflection color and intensity of the supraballs ...

Persistent Luminescence Analysis in the Frequency Domain

open access: yesAdvanced Optical Materials, EarlyView.
A frequency‐domain framework is introduced to characterize persistent luminescence materials. This method surpasses the limitations of time‐domain techniques and provides a new approach to understanding and optimizing the photophysical behavior of complex luminescent systems involving processes with different temporal dynamics.

Origin of Ultraviolet‐Induced High‐Temperature Photovoltaic Response at Pt/Gd‐Doped CeO2 Interface

open access: yesAdvanced Optical Materials, EarlyView.
Oxygen uptake induced by UV irradiation generates an oxygen chemical potential gradient across acceptor‐doped ceria at high temperatures. Besides the photovoltage caused by band bending at the heterojunction interface, the observed voltage can also be attributed to the Nernst voltage arising from the oxygen potential gradient.
