Single phased emission tunable Ca3Si2O7:Ce3+ Eu2+ phosphors for white light emit

A series of single-phased emission-tunable Ca3Si2O7:Ce3+, Eu2+ phosphors has been prepared by the solid-state reaction method. The phosphors show two intense emission bands at about 450 nm and 610 nm, which are attributed to the 5d→4f transitions of Ce3+ and Eu2+ ions, respectively. The emissio
