| مستخلص: | The development of high-sensitivity thermometers has become increasingly important in recent years as the demand for noncontact optical temperature measurement has grown. Herein, we report a series of Sr2ScO3F:Mn4+,Nd3+(SSOF:Mn4+,Nd3+) phosphors synthesized by the traditional high-temperature solid-state method for high-performance temperature sensing. Sr2ScO3F possesses a [ScO6F] octahedron and [SrO9F] tridecahedron, doped Mn4+ions occupy the octahedral sites and emit deep red light at 650–750 nm, and doped Nd3+ions occupy the tridecahedral sites and emit near-infrared light. Due to the energy transfer from the Mn4+to Nd3+ions, the SSOF:Mn4+,Nd3+phosphor exhibits intense dual-center emissions. On the basis of the different thermal quenching behaviors of the Mn4+and Nd3+ions, high-sensitivity ratiometric thermometers can be achieved using fluorescence intensity ratio technology, and the high relative sensitivity (Sr) and absolute sensitivity (Sa) reached 3.40% K–1(at 343 K) and 0.2580 K–1(at 483 K), respectively. Our work not only studies the photoluminescence characteristics of SSOF:Mn4+,Nd3+phosphors but also points out that SSOF:Mn4+,Nd3+phosphors have important potential applications in optical temperature measurement. |
