Enhanced upconversion fluorescent probe of single NaYF(4):Yb(3+)/Er(3+)/Zn(2+) nanoparticles for copper ion detection
Surface modified NaYF(4):Yb(3+)/Er(3+)/Zn(2+) upconversion nanoparticles were obtained by using branched polyethylenimine (PEI). Strong fluorescence emission was observed and the influence of copper ions on the fluorescence emission of the PEI-modified NaYF(4):Yb(3+)/Er(3+)/Zn(2+) nanoparticles was...
