Anion Effect on the Thermometric Properties of Near‐Infrared Emitting Mn5+‐Activated Sr5(PO4)3X (X = F, Cl, Br) Apatite Phosphors

open access: yesAdvanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Mn5+‐activated Sr5(PO4)3X (X = F, Cl, Br) apatite phosphors exhibit tunable near‐infrared thermometric behavior across cryogenic to high temperatures. The correlation between local [PO4]3– geometry and optical properties enables the prediction of suitable hosts directly from structural information.
