A modified wet-chemical synthesis technology was put forward to fabricate Eu 3+ /Dy 3+ doped with YNb x P 1−x O 4 and YNb x V 1−x O 4 phosphors with varying x from the assembly of multicomponent hybrid precursors. The morphologies have been found to be 1–2μm crystalline spheres using XRD and SEM. The red photoluminescence intensity reaches the strongest in YNb 0.8 P 0.2 O 4 :Eu 3+ and YNb 0.1 V 0.9 O 4 :Eu 3+ phosphors and the red to orange intensity ratio (RO) values decrease with the content of P(V) increasing. Besides this, the optimum concentration for Dy 3+ luminescence in YNb 0.5 P 0.5 O 4 is 1mol%, while that in YNb 0.5 V 0.5 O 4 is 0.5mol% or lower than 0.5mol%. The yellow to blue intensity ratio (YB) value of Dy 3+ increases when the Dy 3+ concentration increases from 0.5 to 8mol% in YNb 0.5 P 0.5 O 4 ; however, that of Dy 3+ does not vary much in YNb 0.5 V 0.5 O 4 matrix.
