| Abstract: | KCe(PO3)4 doped with Dy3+,Tb3+,Yb3+and Nd3+ phosphors were synthesized by a solid state diffusion method. The prepared samples were characterized by X‐ray diffraction and photoluminescence. KCe(PO3)4 exhibits emission in ultraviolet (UV) region which indicates weak Ce3+–Ce3+ interaction. The Ce3+–Ce3+energy transfer is not efficient. In light of this, energy transfer from Ce3+ to other lanthanides like Dy3+, Tb3+,Yb3+ and Nd3+ is rather surprising. |
