An efficient green emitting phosphor, Eu2+-doped Ca3SiO4Cl2, is reported. Its excitation band is extending from 260 to 470 nm, which is coupled well with the emission of UV LED (350–410 nm) and blue LED (450–470 nm). It exhibits a strong green emission centered at 505 nm with chromatic coordination (0.25, 0.57), which indicates that it could be a good green phosphor candidate for creating white light in phosphor-converted white LEDs.
