文摘
- •
Eu3+:RGW phosphors were synthesized by the modified sol–gel method.
- •
Exhibits strong red emission at about 616 nm (5D0→7F2) under the excitation of NUV and blue LEDs.
- •
Decay measurement and Judd–Ofelt parameter were calculated and dicussed.
- •
These phosphors are potential candidates as red source for white LEDs application.
