KCe(PO ) doped with Dy ,Tb ,Yb and Nd phosphors were synthesized by a solid state diffusion method. The prepared samples were characterized by X-ray diffraction and photoluminescence. KCe(PO ) exhibits emission in ultraviolet (UV) region which indicates weak Ce -Ce interaction. The Ce -Ce energy transfer is not efficient. In light of this, energy transfer from Ce to other lanthanides like Dy , Tb ,Yb and Nd is rather surprising.
