Abstract
The HEu(MoO4)(2) nanophosphor was synthesized for the first time by the H+-exchange of KEu(MoO4)(2). The nanophosphor obtained in the present study maintain the triclinic KEu(MoO4)(2) type structure in a single phase form with high crystallinity. The HEu(MoO4)(2) phosphor has rod-like particle morphology (length 0.5-20 mu m, diameter 50-400 nm). Both HEu(MoO4)(2) powder and solution shows red emission due to the 4f-4f transition of Eu3+.
