VUV photoluminescence properties of KSrPO4:Dy3+ phosphor

The optimal luminescent sample KSrPO4:1 mol%Dy3+,1.3 mol%Li+ can directly emit warm-white light without two or more luminescent ions co-doped, and its relative luminescent intensity was measured as 60.2% of commercial PDP green phosphor Zn2SiO4:Mn2+ under 147 nm excitation.123
