M9Gd2W4O24:Eu3+ (M2+ = Ca2+ and Sr2+) phosphors were prepared by solid-state reaction, and the phosphors show intense red emission under 395 and 465 run excitations, which matched the emission wavelength of a near-UV (NUV) chip and a blue chip, respectively. Bright white LEDs were fabricated, and the performances of the LEDs demonstrate that the tetra-tungstate phosphors are suitable for application to NUV and blue InGaN-based WLEDs.
