摘要：

Luminous materials with a rapid lifetime response have garnered significant interest in sensing technology. In this work, the transition element Mn doped phosphor Sr2TiO4:Mn4+ was synthesized by a traditional high temperature solid phase method. The emission peak of Sr2TiO4:0.009Mn4+ aligns closely with the absorption peak of phytochrome Pfr. The temperature-dependent photoluminescence (PL) spectra and lifetime of Sr2TiO4:0.009Mn4+ were examined within the temperature range of 273-323 K. The temperature sensing characteristics based on the lifetime were analyzed, and the maximum relative sensitivity was 14.93% K-1 at 309 K. The high sensitivity of the Sr2TiO4:0.009Mn4+ phosphor makes it a promising material for temperature sensing applications. Luminous materials with a rapid lifetime response have garnered significant interest in sensing technology.
