Photoluminescent materials, serving as optical probes, constitute a significant medium for reliable remote sensing of fundamental state parameters such as temperature and pressure. Herein, we report a novel Mn-activated perovskite-type LaMgSbO phosphor (LMS:Mn) for bifunctional application in both thermometry and manometry. Upon excitation with 341 nm, LMS:Mn (0.7 % Mn) emits a bright narrow-band red light peaking at 705 nm with an FWHM (full width at half maximum) of 32 nm. As a thermometer, when the temperature surpasses 298 K, non-radiative transitions from the E excited state lead to a sharp decrease in decay lifetimes with increasing temperature. This allows for lifetime-based luminescence thermometry with a relative sensitivity of 2.52 % K at 391 K. Moreover, LMS:Mn was processed into a temperature-sensing coating and its non-contact thermometry functionality was validated. In manometry applications, the LMS:Mn probe experiences substantial pressure-dependent redshift with a sensitivity of 1.20 nm GPa in the testing range of 9.48 GPa, which is about 3.3 times that of conventional ruby probes. Furthermore, its FWHM consistently remains below 37 nm, which contributes to a high reliability of pressure measurements. The above results indicate that the LMS:Mn constitutes a promising bifunctional luminescence probe material in thermometry and manometry.
