Host Tuned Luminescence Lifetime Thermometers for Imaging Boiling Thermal Dynamics Through Bubbles

open access: yesAdvanced Optical Materials, EarlyView.
The bismuth to vanadate distance is adjusted in solid solutions of ytrrium and scandium orthovanadate to design a lifetime‐based luminescence thermometer with optimal temperature resolution at 100 °C. It is applied on the surface of a boiling channel to observe the thermal signatures of bubble growth and liquid film dry‐out.

Generalized Heterodyne Interferometry in Kerr Materials

open access: yesAdvanced Photonics Research, EarlyView.
Interferometry, combined with heterodyne detection, enables simultaneous measurement of light amplitude and phase. This work applies these methods to study nonlinear phase shifts from the optical Kerr effect during laser pulse propagation. Results show the nonlinear index is straightforward to retrieve at low phases, but at higher powers, pulse shape ...

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

open access: yesAdvanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...
