(Ln3+ = Eu3+/Dy3+/Dy3+, Eu3+) doped NaGd(MoO4)2 phosphors with uniform morphologies: Hydrothermal synthesis, luminescent properties, energy transfer and color tunable emission

The Dy3+, Eu3+ co-doped NaGd(MoO4)2 powders with yellow-to-white-to-pink color shift are successfully synthesized by adjusting the concentration of Eu3+ in the phosphor. And the energy transfer mechanism from Dy3+ to Eu3+ belongs to dipole-dipole interaction in the samples.181
