摘要：

Sr5(PO4)3F phosphor doped with Eu[image omitted] and Ce[image omitted] ion were prepared by combustion synthesis. Under UV excitation (254 nm) Sr5(PO4)3F:Ce exhibits Ce[image omitted] UV emission (355 nm) and under 354 nm, Sr5(PO4)3F:Eu exhibits Eu[image omitted] emission (440 nm). The aim of this article is to report energy transfer mechanism between Ce[image omitted]Eu[image omitted] ion in Sr5(PO4)3F:Ce,Eu phosphors, where Ce ion act as sensitizer and Eu act as activator. Ce emission energy band is in resonance with Eu excitation energy band. Their structures properties and photoluminescence spectra were systemically studied. This article includes synthesis of phosphor, XRD, EDS, SEM pattern of host lattice, photoluminescence behavior, and energy transfer mechanism between the two rare earth ions.
