The intense red‐emitting phosphor Na0.5Gd0.5MoO4:Eu3+ with tetragonal structure was prepared by solid‐state reaction and its photoluminescence properties were investigated. Compared with Y2O2S:0.05Eu3+, the obtained Na0.5Gd0.375MoO4:Eu0.1253+ phosphor shows a stronger excitation band near 400 nm as well as enhanced red emissions. The strong red‐emission lines at 616 nm correspond to the forced electric dipole 5D0→7F2 transitions on Eu3+. The chromaticity coordinates of Na0.5Gd0.375MoO4:Eu0.1253+ (x=0.652, y=0.348) are closer to the standard of National Television Standard Committee values (x=0.670, y=0.330) than that of Y2O2S:0.05Eu3+ (x=0.645, y=0.354). The optical properties suggest that Na0.5Gd0.375MoO4:Eu0.1253+ is an efficient red‐emitting phosphor for light‐emitting diode applications.
