摘要
对高温固相法制备的新型长余辉发光材料Y2O2S∶Eu,Mg,Ti,通过分析其激发光谱和发射光谱发现,主要是由Eu,Mg,Ti的掺杂引起激发波峰加强并红移,产生了纯正的红色长余辉.该发光材料适合紫外光和可见光激发,具有广泛的应用前景.
Eu^3+-activated Y2O2S phosphor co-doped with Mg and Ti ions were synthesized by the high-temperature solid state method. By analyzing excitation curve and emission curve, the performance of the long afterglow was found because the coaction of Eu, Mg, Ti ions. The phosphor can be used in a large area and has a good application.
