New HEu1-xGdx(MoO4)2 nanophosphors were synthesized by a simple one-step ion-exchange method. These nanophosphors have rod-like particle morphology with 0.5–15 μ m in length and outer diameters in the range of 50–500 nm. By optimization of the composition, the highest emission intensity was obtained for the samples with x = 0.50 for both KEu1-xGdx(MoO4)2 and HEu1-xGdx(MoO4)2.
