    Abstract

    It has been found that Mn4+-activated La2MTiO6 (M = Mg and Zn) functions as novel Eu-free phosphors for red emission in this work. La2MTiO6:Mn4+ exhibited emission with a peak at 710 nm under excitation by ultraviolet to blue light (300-550 nm). La2MgTiO6:Mn4+ exhibited stronger emission than La2ZnTiO6:Mn4+. The internal quantum yield of La2MgTiO6:Mn4+ was 58.7% under the excitation at 330 nm.
