Eu3+,Mn4+掺杂Ba2SrWO6荧光粉的发光性能及温度传感特性
Luminescence Properties and Temperature Sensing Characteristics of Eu3+,Mn4+Doped Ba2SrWO6 Phosphors
摘要
Abstract
In the study,a series of Eu3+and Mn4+singly doped and co-doped Ba2SrWO6 phosphors were successfully synthesized by high-temperature solid-state reaction method.The crystal structure,sample morphology,and spectral properties of the phosphors were characterized and analyzed using X-ray diffraction,scanning electron microscopy,and spectral analyzer.The results indicate that doping with Eu3+and Mn4+does not alter the crystal structure of Ba2SrWO6,with all samples maintaining a single pure phase.Under 325 nm excitation,Ba2SrWO6:Eu3+/Mn4+phosphors exhibit significant red emission,including the 5D0→7F1characteristic transition of Eu3+at 594 nm,the 5D0→7F2 characteristic transition at 615 nm and the 2Eg→4A2g transition of Mn4+at 695 nm.The emission peak positions in the co-doped system are consistent with those of the singly doped system.The composition with the highest luminous intensity is Ba2SrWO6:7%Eu3+/0.6%Mn4+.Within the temperature range of 300~500 K,based on the fluorescence intensity ratio(IEu/IMn),the maximum relative sensitivity reaches 0.87%K-1 at 300 K,and the maximum absolute sensitivity is 0.005 9 K-1 at 510 K.These results demonstrate that Ba2SrWO6:Eu3+/Mn4+phosphors are used as candidate materials for efficient optical temperature sensing.关键词
