Abstract

A down-conversion luminescent material GdPO4-Gd3PO7:Eu3+ has been synthesized by Pechini sol-gel process. The XRD patterns indicated that the obtained powders have a mixed crystalline phase. An intense luminescent red emission was obtained upon excitation 275 nm. The influence of different synthesis conditions on morphology and the PL emission ratio I(5D0 → 7F2)/I(5D0 → 7F1) was established.
