摘要：

A series of novel SrMg(PO):Ce,Tb(SMP:Ce,Tb) phosphors with tunable emission spectra were produced via high temperature solid phase method.XRD,fluorescence spectrum and fluorescence lifetime for SMP:Ce,Tbwere studied in detail.Under the excitation at 308 nm,SMP:Ce,Tbsamples can emit high efficiency tunable blue-green light by controlling the proportion of dopant concentration.Through the spectral overlap and the regular change of fluorescence lifetime,it is proved that there is a significant energy transfer between Ceand Tbin SMP matrix and the energy transfer mechanism is determined to be an electric dipole-dipole interaction with energy transmission efficiency of 55%.In additional,Commission International de L’Eclairage(CIE) color coordinates and thermal stability were studied.All above findings suggest that SMP:Ce,Tbcan be regarded as the potential bluish green phosphor for LED applications.
