Eu3+-activated novel red phosphors, MLa2(MoO4)(4) (M = Ba, Sr and Ca) were synthesized by the conventional solid state method. The excitation and emission spectra indicate that these phosphors can be effectively excited by UV (395 nm) and blue (466 nm) light, and exhibit a satisfactory red performance at 614 nm. Upon excitation with a 466 nm light, Our synthesized phosphors have stronger emission intensity than the sulfide red phosphors used in white LEDs. Due to high emission intensity and a good excitation profile, the Eu3+-doped CaLa2(MoO4)(4) phosphor may be a promising candidate in solid-state lighting applications.
