In this study, down-conversion fluorescent powder of Sr2ZnSi2O7:Eu2+,Dy3+, SrAl2O4:Eu2+,Dy3+ and Y2O2S:Eu3+,Mg2+,Ti4+, which were the common three primary colors materials with long afterglow, were synthesized by high temperature solid state method. The blends of rare earth (RE) luminescent materials have been of interest to reinvest the luminescent characteristics of polyethylene terephtahalate (PET)...
A ternary luminous fiber with white light emitting was prepared. The fiber combined emission from Sr2ZnSi2O7:Eu2+,Dy3+, SrAl2O4:Eu2+,Dy3+ and Rhodamine B in the ternary system. According to fluorescence resonance energy transfer (FRET), Rhodamine B was applied to generate red emission. A novel FRET system among Sr2ZnSi2O7:Eu2+,Dy3+, SrAl2O4:Eu2+,Dy3+ and Rhodamine B was introduced. The anticipated...
