New insight into the structure evolution and site preferential occupancy of Na2Ba6(Si2O7)(SiO4)2:Eu2+ phosphor by cation substitution effect

The photoluminescence of Eu2+ could be efficiently controlled via the structure evolution by substituting Mg2+/Zn2+ for Ba2+ in Na2Ba6(Si2O7)(SiO4)2 host.262
