- •
EuxY6–xWO12 (x = 0.1–1.0) phosphors were synthesized via a solid-state reaction.
- •
Strongest excitation peaks observed at 392 nm (near UV) and 463 nm (blue).
- •
The major emission peak of the red phosphor excited by 392 nm was at 605 nm.
- •
The quantum efficiency of EuxY6–xWO12 (x = 0.1–1.0) phosphors had been done.
