Luminescence properties and energy transfer from Eu2+ to Tb3+ in Sr5(PO4)3F phosphor

摘要：

　　A series of single-phase Srs(PO4)3F∶ Eu2+,Tb3+,Na+ phosphors have been synthesized by high temperature solid-state reaction.The photoluminescence excitation and emission spectra,concentration effect and energy transfer from Eu2+ to Tb3+ are investigated in detail.The work shows that there is an effective energy transfer from Eu2+ to Tb3+,where Eu2+ reveals an intense excitation band from 280 nm to 400 nm,matching well with the emission of n-UV chips,and Tb3+ emits an intense green emitting light.
