摘要: Abstract The NaBaPO4:Eu2+,Yb3+ quantum-cutting (QC) phosphors were prepared by the solid-state reaction. We confirm luminescence of Yb3+ is mainly derived from QC rather than common down-conversion. efficiency ηQE calculated decay curves reached a maximum as high 197.4%. Furthermore, emission was enhanced decorating with quasi-spherical and uniform (∼100 nm) Ag nano-particles, due to localized surface plasmon resonance. enhancement factor 1.2337.
