Tricolor emission Ca3Si2O7:Ln (LnCe, Tb, Eu) phosphors for near-UV white light-emitting-diode

► Tricolor Ca3Si2O7: Ln phosphors were demonstrated to construct near-UV white LED. ► Eu2+ doped Ca3Si2O7 red-emitting phosphor was confirmed by this work once again. ► Thermal quenching properties for Ca3Si2O7:Ln phosphors were reported for the first time. ► Performances of fabricated white LED indicated the potential application of phosphors.
