- •
Dual-emitting LaOBr: Ce3+, Tb3+ phosphor is studied to realize ratiometric temperature sensing.
- •
The intensity ratio of Ce3+ and Tb3+ emission is used as the thermometric parameter (Δ = ICe/ITb).
- •
LaOBr: Ce3+, Tb3+ has wide temperature sensing range (293–443 K) with sensitivity of 0.42% K−1.
- •
This research might provide a new path for the exploration of luminescent temperature sensors.
