- •
GdY(MoO4)3:RE3+ (RE = Eu, Dy, Sm, Tb) phosphor were synthesized via a Pechini-type sol–gel process.
- •
Under the excitation, the GdY(MoO4)3:RE3+ phosphors exhibit the characteristic RE3+ emission.
- •
The concentration quenching is not observed in the GdY(MoO4)3:xEu3+ system.
- •
The emission intensities maximize at x = 0.05, 0.03, and 0.18 for Dy3+, Sm3+, and Tb3+ in the host.
- •
The PL colors of GdY(MoO4)3:0.01Tb3+, xEu3+ samples can be tuned from green to red.
