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

open access: yesAdvanced Optical Materials, Volume 13, Issue 36, December 19, 2025.
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.
