A new method was developed for selective and sensitive determination of trace chromium (VI) based on the inner filter effect (IFE) of upconversion luminescent nanoparticles (NaYF(4):Yb(3+), Er(3+)) as fluorescence probes. In this study, water-soluble and well dispersible upconversion luminescent nanoparticles (NaYF(4):Yb(3+), Er(3+)) were firstly… CONTINUE READING
