“…So, the researcher needs to develop single host white phosphor material that can be illuminated with near ultraviolet or ultraviolet sources. In literature, the light colour tailoring luminescence characteristics of Eu 3+ and Dy 3+ have been investigated in some hosts such as Ca 2 P 2 O 7 :Eu 3+ /Dy 3+ [10], BaB 2 Si 2 O 8 : Eu 3+ /Dy 3+ [11], and NaGd(MoO 4 ) 2 : Dy 3+ /Eu 3+ [12], etc.…”
